腹筋崩壊

• Reading: ふっきんほうかい
• Romaji: fukkin hōkai
• Kanji breakdown: 腹 (belly) + 筋 (muscle) + 崩 (crumble) + 壊 (break)
• Pronunciation: /ɸuk.kiɴ hoː.ka.i/

Meaning

Abs collapsed — laughed so hard your stomach muscles gave out, the Japanese internet's most dramatic way to say something is uncontrollably hilarious.

腹筋崩壊 takes the physical sensation of laughing until your abs hurt and cranks it up to apocalyptic levels: your abdominal muscles have literally collapsed. It is a staple internet tag and reaction phrase, often used as a hashtag (#腹筋崩壊) on funny videos and posts. The phrase works because 崩壊 (collapse/disintegration) is normally reserved for serious things like building collapses or nuclear meltdowns, creating an absurd contrast when applied to laughing at a cat video.

Examples

1. この動画腹筋崩壊するから電車で見ないほうがいいよ。 Don't watch this video on the train — it'll destroy your abs from laughing.
2. 友達のモノマネが上手すぎて腹筋崩壊した。 My friend's impression was so good it wrecked my abs.
3. 深夜に腹筋崩壊系の動画見るのやめられない。 I can't stop watching abs-destroying videos late at night.

Don't Say
