Dysfunctional players, Stories? Options

[emo samurai]

I'm not talking about C.L.U.E. files material or simple pvp conflict; I'm talking about annoying ass habits.

I have one player who repeats shit all the time. He has a character who used to be part of Knight Errant and was discharged to appease the media after killing a good merged little girl. When fighting a beetle spirit, he used a Knowledge: Insect Spirits check to find its weak spot (its neck).

This wasn't a problem in and of itself, except for the fact that he repeated "You see that? I knew its weak spot!" about five fucking times.

Oh, and he thinks he has ESP and used it to find out his military call sign, which is "shadow." He also names his character "Shadow," because he's shadowy.

Another player is playing a snake shaman named "Cobra," so named because "He slithers." He repeated this about five times during character creation. He also said "So when the smoke clears and everything, you're gone, because my character will shapeshift you. He'll benefit everybody" about five fucking times.

Anyone care to chime in with tales of extreme player social ineptitude?
