qwertyfacing
Typing while half asleep, or being in that fugue state between half-awake and half-asleep while chatting. Used mostly while excusing oneself from chat to go to bed (or when one is chatting well past one's bedtime).
Sorry, gotta go pass out now. I'm qwertyfacing.
qwertyface
Falling asleep while infront of a computer, usually resulting in the usage of a keyboard for a pillow.
I played Counter-Strike for so 7 hours last night, then qwertyfaced.
