RoMicide describes the practice of banning anybody related to the CAD comic (Ctrl + Alt + Del) "RoM incident", wherein some rather nasty rumours about the comic's artist were leaked, and in reaction, the artist deleted an entire subsection of the forum (Known as RoM, or Rantings of Madmen), and banned everybody involved. So, FalconX, a "RoMite" created his own forum, where the banned "RoMites" could hang out. Following this, everybody who mentions the incident or the URL for the new RoM forums are instantly "permabanned" (permanent ban).
"Chomber commited RoMicide."
In response, Tim shut down the "Rantings of Madmen" section of the forum, and exterminated many of the RoM posters. Even though the moderators on the CAD forums attempted to save the community, they too were banned. By doing this, he proved the rumor as true.
Forum Goer Two: The RoMicide. Now there's no one left here.
Moderator One: Stay on topic.
Admin: ****, you know what, you're banned now too. **** this **** I'm a rockstar with a thousand fans that doesn't need this crap.
