ワンパン

• Reading: ワンパン
• Romaji: wanpan
• Pronunciation: /waɴ.paɴ/

Meaning

One-shot kill — defeating an enemy or being defeated in a single hit, emphasising overwhelming power or fragility.

ワンパン combines ワン (one) and パンチ (punch) to describe a one-hit knockout. In gaming, it describes either an overpowered attack that kills in one blow or a fragile enemy that goes down instantly. The popularity of the anime 'One Punch Man' (ワンパンマン) further cemented this term in mainstream culture. Players use it both to brag about their damage output and to complain about unfair enemy attacks.

Examples

1. そのボス、ワンパンで倒せたわ。レベル上げすぎたかも。 I one-shotted that boss. Maybe I over-leveled a bit.
2. え、ワンパンで死んだんだけど？この敵やばくない？ Wait, I got one-shotted? Isn't that enemy way too strong?
3. このキャラの火力やばい、雑魚敵全部ワンパンだよ。 This character's damage is insane — every trash mob gets one-shotted.

Don't Say

• 現実の暴力にワンパンを使うと軽く聞こえるので避ける (Avoid using ワンパン for real-world violence — it trivialises the situation)
