Threadshitting is belittling the topic or the people discussing it on a message board. It typically takes the form of a dismissive comment, like “Who cares?” or “This is stupid!” or similar. The implication of the threadshitter is that discussion of such a topic is beneath them, and should be beneath everybody else.
Once again, Whack-a-Mole was being a complete dick and threadshit on what should have been a fun thread.
