デブ

• Reading: デブ
• Romaji: debu
• Kanji breakdown: Etymology uncertain. Written in katakana. Possibly onomatopoeic or from English 'double'
• Pronunciation: /de.bɯ/

Meaning

Fat, overweight — a blunt and rude insult about someone's body size.

デブ is a crude, direct term for someone who is overweight. While it's considered rude when directed at others, many Japanese people use it in self-deprecating humour (自分のことデブって言う). The word exists in a culture where being thin is strongly valued and body-shaming, while criticised, remains common. The boundary between light self-deprecation and harmful insult depends heavily on context and who is speaking.

Examples

1. 最近デブになったから、ダイエットしないと。 I've gotten fat lately, so I need to go on a diet.
2. デブって言わないで、ぽっちゃりって言って。 Don't call me fat — say 'chubby' instead.
3. 自分のことデブって言うのは自虐ネタとして成立するけど、人に言うのはアウト。 Calling yourself fat as a self-deprecating joke is fine, but saying it to others is out of line.

Don't Say

Common Mistakes
