LMAO...there is actually serious discussion about this..I love AT
Anyway...I can't even fathom using stuff like "w00t" or "lol" in real life...then again, I use "0wn" all the time now (damn CS

)...
But I use "Nice", "kick-ass", or "bitchin'" all the time, or "excellent" with the requisite "Burns" impression.
