じわる

• Reading: じわる
• Romaji: jiwaru
• Pronunciation: /dʑi.wa.ɾɯ/

Meaning

Slowly becoming funny — a delayed, creeping sense of humour that gradually builds until you can't help laughing.

From じわじわ来る (jiwa jiwa kuru, 'it comes gradually'), じわる describes humour that doesn't hit you immediately but sneaks up on you. The joke or image keeps replaying in your mind and becomes funnier each time. It contrasts with explosive 爆笑 laughter — じわる is a slow burn. Very popular on social media when sharing subtly funny content.

Examples

1. この動画、最初は普通だったけどだんだんじわってきた。 This video seemed normal at first, but it gradually got funnier and funnier.
2. 友達が送ってきた写真がじわるんだけど。 The photo my friend sent me is one of those slow-burn funny ones.
3. あのCMじわるよね、何回見ても笑っちゃう。 That commercial is a slow burn, right? I laugh every time I watch it.
