イッチ

• 読み: イッチ
• ローマ字: icchi
• 発音: /it.tɕi/

意味

Thread starter or original poster (OP), derived from いち (one/first) — the person who created the thread.

イッチ is なんJ slang for the thread starter, the person who posted the first message (>>1). It comes from いち (one/first) with a playful katakana rendering. On boards like なんJ, the thread starter often sets the topic and tone, and other users may reference them as イッチ when responding. It functions similarly to 'OP' in English internet culture. The term has spread beyond 2ch/5ch to general internet usage.

例文

1. イッチの質問に答えるけど、それは無理だと思う。
2. イッチがスレ立ててからもう3時間経ってるぞ。
3. イッチ、もうちょっと詳しく教えて。
