ちーっす

• 読み: ちーっす
• ローマ字: chiissu
• 発音: /tɕiːs.sɯ/

意味

A very casual, slurred greeting meaning 'hey' or ''sup' — a lazy version of こんにちは used among young men.

ちーっす is what happens when こんにちは gets run through a blender of casualness. The abbreviation chain (こんにちは → ちわっす → ちーっす) strips away all formality, leaving a greeting that is pure casual energy. It is associated with young men, especially in sports clubs, part-time jobs, and casual hangouts. The elongated vowel adds a laid-back, almost comedic quality.

例文

1. ちーっす、今来たとこ。
2. ちーっす先輩、今日も暑いっすね。
3. あ、ちーっす。何してんの？
