An individual whose very presence lowers the tone in the room. Will complain about almost anything and will dress in plain, understated clothes. The human equivilent of Eeyore from Winnie the Pooh.
"Hi everybody. Hope you're feeling better today than I am. Still can't find my Prozac anywhere, I'm getting really worried now. Must the Sun rise every morning in the east? Why can't..." - ad infinitum.

Lisa only calls me when she wants to complain about how bad her life is. I'm tired of being her sad sack.

A person who goes by a false name. Works at a company where he is just an extension and likes to think of himself as a Loner where he is infact just a social reject with friends.
