Can be referred to as an IRC Wraith. Goes chat to chat sucking the fun and goodness out of a great chat and making it horrible and lame and unbearably shitty in his presence. The cure is to remove the wraith from the room. Symptoms should clear up shortly.
"Why's this chat so shitty?" "..Oh god, nihilanthic's here."
