スレ主

意味

Thread starter or original poster — the person who created the thread (スレッド) on a message board.

スレ主 combines スレ (sure, short for スレッド/thread) and 主 (nushi, master/owner). It identifies the person who started a discussion thread on 2ch/5ch or similar forums. Functionally identical to イッチ but more widely understood outside of なんJ culture. The スレ主 sets the topic and often moderates the conversation. The term has spread to general internet usage, sometimes applied to the person who started a discussion on Twitter/X or other platforms.

例文

1. スレ主はもう来ないのかな。
