Back when I first got a computer, back when the Unreal Tournament demo was the thing to play, I used the corpse looking model, and promptly called myself deadman.
Ever since then, in every chat, in every forum, in every non-rpg game, I have called myself deadman.
I've developed a kind of deadman personae with that name, although personae is probably too strong a word, but anyway.
I've become so strongly attached to this name that if I can't create an account (on a site, in a game, whatever) using it, I seriously re-consider making that account. The #massassi move nearly left me behind, because Deadman was already taken, but the other Deadman that dwells there doesn't seem to be on whenever I am, so I make do.
