Hello, I’m Kodak.
If you watch anime or Japanese gaming videos, you may hear a character lose a fight and shout:
Kuso!
Both can be correct.
Kuso literally means feces, excrement, or roughly “shit.” It is also used as an emotional shout like “Damn!”, as an insulting prefix meaning “shitty”, and as a rough intensifier meaning “extremely” or “ridiculously.”
Quick answer
糞／くそ／クソ (kuso) basically means “feces” or “shit.”
Depending on context, it can also mean:
・“Damn!” or “Damn it!”
・“crap” or “shitty”
・a contemptuous prefix added to an insult
・an informal intensifier meaning “extremely” or “ridiculously”
クソガキ (kusogaki) is a strong derogatory expression for a child or young person, commonly translated as “damn brat,” “little shit,” or “stupid brat.”
This article explains kuso meaning in Japanese, kuso in anime and slang, kusogaki meaning, pronunciation, spelling, origin, grammar, strength, and natural example sentences.
What Does Kuso Mean in Japanese?
Hiragana: くそ
Katakana: クソ
Romaji: kuso
Basic meanings:
1. feces / excrement / poop / shit
2. bodily dirt or residue in compounds
3. something worthless or terrible
4. “Damn!” as an emotional exclamation
5. a prefix expressing contempt or an extreme degree
1. Kuso as a Literal Noun: Feces or Excrement
道に犬の糞が落ちていた。
Michi ni inu no kuso ga ochite ita.
There was dog poop on the road.
靴で糞を踏んでしまった。
Kutsu de kuso o funde shimatta.
I accidentally stepped in poop with my shoe.
Usually, うんち (unchi) or うんこ (unko) sounds more child-friendly or casual.
Kuso feels rougher and more vulgar, especially when used by itself.
2. Kuso as an Exclamation: “Damn!” or “Shit!”
When something goes wrong, くそっ！ can express anger, frustration, pain, or disappointment.
くそっ、また負けた！
Kuso, mata maketa!
Damn it, I lost again!
くそ、間に合わなかった。
Kuso, maniawanakatta.
Damn, I didn’t make it in time.
Not in every scene. English subtitles may choose “damn,” “damn it,” “crap,” or “shit” depending on the character and rating.
There is no perfect one-to-one profanity scale between languages.
3. Kuso as “Worthless,” “Terrible,” or “Shitty”
Kuso can be placed before a noun to show contempt for it.
a shitty / terrible movieクソアプリ
a terrible app
クソ仕事
a shitty job
クソ上司
a horrible boss
クソルール
a stupid / terrible rule
なんだ、このクソ映画。
Nanda, kono kuso eiga.
What is this terrible movie?
このクソアプリ、また落ちた。
Kono kuso apuri, mata ochita.
This shitty app crashed again.
Often, yes. クソ＋noun can show that the speaker considers the noun bad, worthless, annoying, or contemptible.
But Japanese also uses kuso in fixed expressions and as a degree intensifier, so “shitty” will not fit every compound.
4. Kuso as an Intensifier: “Extremely” or “Ridiculously”
In rough casual speech and online slang, kuso can strengthen an adjective.
damn hot / ridiculously hotクソ寒い
damn cold / freezing
クソ眠い
damn sleepy / extremely sleepy
クソうまい
insanely delicious / damn good
クソ強い
absurdly strong
クソかわいい
ridiculously cute
今日、クソ暑くない？
Kyō, kuso atsuku nai?
Isn’t it ridiculously hot today?
このラーメン、クソうまい。
Kono rāmen, kuso umai.
This ramen is insanely good.
Here it no longer means the food or person is bad. It adds rough emotional force, similar to “damn,” “insanely,” or “ridiculously.”
The expression is still very casual and can sound crude.
Is Kuso a Swear Word?
Kuso is vulgar language. Its severity varies with how it is used.
くそ、忘れた。
Damn, I forgot.Angry exclamation:
くそっ！ ふざけるな！
Damn it! Don’t mess with me!
Insulting prefix:
このクソ野郎。
You piece of shit. / You bastard.
Rough intensifier:
クソ疲れた。
I’m damn tired.
It is safer not to. Even when it is not aimed at a person, it sounds crude and emotionally uncontrolled.
At work, use phrases such as 困ったな (“That’s a problem”), またエラーだ (“Another error”), or 使いにくい (“It’s difficult to use”).
Kuso Meaning in Anime and Manga
Anime subtitles may translate kuso differently depending on the scene.
Damn! / Damn it! / Shit!くそ、逃げられた。
Damn, they got away.
このクソ野郎！
You bastard! / You piece of shit!
クソみたいな世界だ。
This world is shit. / What a terrible world.
クソ強い。
He’s insanely strong.
そんなクソみたいな命令、聞けるか！
Why should I obey such a bullshit order?
Subtitles translate the force and function of the line, not only the dictionary word.
A translator considers the character, age rating, anger level, sentence rhythm, and what sounds natural in English. This does not mean kuso always equals one particular English swear word.
It is real Japanese, but anime often makes the volume, timing, and emotion more dramatic.
In real life, many people avoid saying it publicly or in polite company.
What Does Kusogaki Mean?
クソガキ (kusogaki)
クソ (kuso) = shit / damn / contemptible
＋
ガキ (gaki) = brat; a derogatory word for a child
↓
クソガキ = damn brat / little shit / stupid brat
Kusogaki is used to insult a badly behaved, rude, annoying, arrogant, or disrespectful child or young person.
このクソガキ、どこ行きやがった？
Kono kusogaki, doko iki yagatta?
Where did that damn brat go?
生意気なクソガキだ。
Namaiki na kusogaki da.
He’s an insolent little brat.
The structure is roughly “shit + brat,” but natural English translations are usually “damn brat,” “little shit,” or “stupid brat.”
Word-for-word translation is less useful than matching the level of contempt.
How Strong and Rude Is Kusogaki?
Kusogaki is strongly derogatory. It does not simply mean “child.”
child — neutralガキ (gaki)
brat / kid — rough and contemptuous, though friends may use it jokingly
クソガキ (kusogaki)
damn brat / little shit — stronger contempt
悪ガキ (warugaki)
naughty child / little rascal — can be critical but is often lighter than kusogaki
Some people may use it jokingly in a very familiar relationship, but that does not make it a neutral family word.
It remains insulting language, and a learner should not use it toward someone else’s child.
Where Does Gaki Come From?
餓鬼 (gaki) originally refers to a hungry ghost in Buddhist belief—a being that suffers from constant hunger and thirst.
From the image of greedily seeking food, gaki later became a contemptuous word for a child.
hungry ghost in Buddhism
↓
a person who greedily devours food
↓
a derogatory term for a child
↓
ガキ = brat / kid
↓
クソガキ = damn brat / little shit
No. Modern speakers normally use gaki as the established rough word “brat” or “kid.”
The Buddhist meaning explains its historical background, not the image in every modern conversation.
Kusogaki Meaning in Anime, Manga, and Games
In fiction, kusogaki is often used by an angry adult, rival, criminal, soldier, or rough-speaking older character.
You little shit! / You damn brat!生意気なクソガキめ。
You insolent little brat.
クソガキのくせに。
You’re just a damn kid.
あのクソガキ、また勝手なことを。
That damn brat is doing whatever he wants again.
Often, but not necessarily a small child. An older speaker may insult a teenager or even a young adult as a disrespectful “brat.”
The word can emphasize the age and status difference as much as actual childhood.
How to Write Kuso and Kusogaki
Kanji spelling of kuso. Common in dictionaries and literal references to excrement.くそ
Hiragana. Often used in ordinary prose, emotional writing, or when the kanji would feel visually heavy.
クソ
Katakana. Very common for insults, slang, manga dialogue, internet comments, and emphatic compounds.
糞餓鬼／糞ガキ／クソガキ／くそガキ
Possible spellings of kusogaki. クソガキ is especially clear and common in casual visual writing.

How to Pronounce Kuso and Kusogaki
Mora: く・そ (2 morae)くそがき (kusogaki)
Mora: く・そ・が・き (4 morae)
Pronounce every Japanese beat clearly. The first syllable is not the English word “coo,” and the final vowel in kuso should not be turned into an English diphthong.
The Origin and Etymology of Kuso
Kuso is a very old Japanese word. The reading appears in ancient Japanese texts, including the Kojiki, compiled in 712.
The modern kanji 糞 literally refers to excrement. Dictionaries also record long-established figurative meanings such as something worthless, contemptible, or insignificant.

something dirty, worthless, or contemptible

an insult or angry exclamation

No. The word and its insulting or figurative uses are much older than anime.
Anime, manga, games, and online culture simply make these uses highly visible to international learners.

Common Beginner Mistakes
Mistake 1: Translating Every Kuso as “Shit”
dog poop / dog fecesくそっ！
Damn it!
クソ映画
a terrible / shitty movie
クソうまい
insanely good
クソガキ
damn brat / little shit
Mistake 2: Assuming It Is Safe Because Anime Uses It Often
Frequency in fiction does not make a word appropriate in class, at work, or with strangers.
Mistake 3: Using Kusogaki as a Funny Word for Any Child
Kusogaki expresses strong contempt. Use 子ども for the neutral meaning “child.”
Mistake 4: Believing Katakana Is the Only Correct Spelling
糞, くそ, and クソ are all possible. Katakana is especially common for visual emphasis and slang.
Mistake 5: Copying One English Profanity Level
Japanese and English profanity systems do not align perfectly. Translate the function and emotion of the whole line.
Mistake 6: Using Kuso as an Intensifier in Polite Japanese
A sentence may use polite verb endings and still sound crude if it includes kuso.
