ぐう畜

• Reading: ぐうちく
• Romaji: guu chiku
• Kanji breakdown: ぐう (from ぐうの音も出ない, undeniably) + 畜 (livestock/beast, from 畜生) → undeniably beastly
• Pronunciation: /ɡɯː.tɕi.kɯ/

Meaning

A criticism meaning 'genuinely terrible/scummy' — used to describe someone who is undeniably awful or behaves badly.

ぐう畜 combines ぐう (from ぐうの音も出ない, undeniably) with 畜 (from 畜生, beast/scum). It is the negative counterpart to ぐう聖. Used on forums and social media to describe people or characters who do something so selfish, cruel, or appalling that there is no defending them. Often used humorously about fictional characters or celebrities, but can be genuinely critical.

Examples

1. 浮気がバレてもヘラヘラしてるとかぐう畜。 He got caught cheating and just laughed it off — genuinely scummy.
2. あいつ友達の弁当勝手に食べたらしい。ぐう畜すぎ。 Apparently that guy ate his friend's lunch without asking. Absolute trash.
3. このキャラの裏切り方がぐう畜で草。 The way this character betrayed everyone is so scummy, I'm dying.
