Running gag. We have a certain member who uses first person plural way more than he should, in an attempt to convince people he's no longer there and has been replaced entirely by an entirely different group of people who just happen to post in his same idiosyncratic style, share his idiosyncratic interests, and seem oddly oversensitive to people who even accidentally use the name of his former singular identity.
So this has spawned a team of tongue-in-cheek copycats, naturally.
