the old classic unique tech-isms
gdd - God (as an exclaimation), dick (what i'm calling you), die (the directive). has not been in use too often as of late. brian lee made an alternate form calling someone a dd (dick die, as a noun)
tityta - this still means this is tech you're talking about. probably will be used more often when starcraft 2 is released (additionally, tisatyta, as in this is scout [my roommate] and tech you're talking about, this would be our team name in vid games. personally i think this is tech and scout you're talking about sounds better but tisatyta does sound better than titasyta)
sbsan - stop being such a newb (see below for newb explanation)
hhw - hey hey, wah (the first two heys are a quick 16-th note like staccato and then an elongated WAH, to emphasize the futility of your whining)
wdycai - why don't you cry about it (usually said after a hhw)
currently used phrases
lol/lawl/lowl/lulz/lul - pretty much a standard phrase with now many dialects of usage indicating something that is funny, i tend to use lowl now most often at the moment, but am able to use any at any time.

MR - so this actually came from my dad who told a somewhat funny story of a patient because he was trying to communicate with him but failed to see at the bottom of the clipboard that he was MR. you can guess what this means, it's a bit politically incorrect. example:
my sister: "Hey what's 3% of 100?"
me: "Are you MR?"
