亀レス

• 読み: かめレス
• ローマ字: kame resu
• 漢字の分解: 亀 (turtle) + レス (response) → turtle-speed response
• 発音: /ka.me.ɾe.sɯ/

意味

A very late reply to a message or forum post — literally 'turtle response,' acknowledging the slowness.

亀レス combines 亀 (kame, turtle) with レス (resu, from English 'response'). It describes replying to a message long after it was sent — like a turtle slowly arriving. It is often used as a self-deprecating preface when finally responding to an old message: '亀レスだけど…' (turtle response but…). Common in both forum culture (replying to old threads) and personal messaging (finally texting back days later).

例文

1. 亀レスごめん！今やっと見た。
2. 亀レスだけど、あの件どうなった？
3. 3日ぶりに返信とか亀レスすぎてごめん。
