Meaning

To chill, to relax — borrowed directly from English 'chill' and used as a trendy way to describe unwinding.

Borrowed from English 'chill,' チル entered Japanese youth vocabulary through hip-hop and music culture in the 2010s. チルする means 'to chill out' — spending relaxed, low-key time. It can describe the activity (カフェでチルする = chilling at a café) or the vibe (チルな音楽 = chill music). It carries a fashionable, urban connotation.

Examples

1. 今日はカフェでチルしてた。最高だった。 I was chilling at a café today. It was the best.
2. 週末は家でチルするのが一番幸せ。 Chilling at home on the weekend is pure happiness.
