Octothorp - A lazy person who sits in the lobby all day waiting for some

A lazy person who sits in the lobby all day waiting for someone to log on so they can call that person a cheater and feel better about themselves.

I sat in the lobby for three hours just to yell at someone for being a cheater.

I waited for my friend to log on so I could call him a quitter.

I called my brother a cheater because he beat me, even though I didn’t log on.
