MrMouse

The act of bigging oneself up unnecessarily through a gaming headset and not being unwilling to do so in person. Squeaking loudly through said device.

I was on the PS3 last night and everyone was giving it MrMouse at me.

MrMouse

A loud mouth, obnoxious, irritating southerner who talks crap and just can't help themselves.

Did you here MrMouse talking crap, what a dick!
