ROM専

• 読み: ロムせん
• ローマ字: romu sen
• 漢字の分解: ROM (Read Only Member) + 専 (exclusive/only) → someone who exclusively reads without posting
• 発音: /ro.mu se.n/

意味

A lurker — someone who only reads content without posting, commenting, or participating actively.

ROM専 combines ROM (Read Only Member/Memory) with 専 (sen, exclusive/only). It describes people who observe online communities without ever contributing content themselves. ROM専 is not inherently negative — many communities accept that most members are lurkers. However, when a community needs active participation, being ROM専 can be seen as freeloading. The phrase 'ROM専でもいいから' (even just lurking is fine) is sometimes used to welcome shy newcomers. In streaming, ROM専 viewers watch without commenting in chat.

例文

3. あのコミュニティROM専ばっかりで過疎ってる。
