Verb, meaning to completely dominate something. Comes from the card game Bridge, where the best strategy that ever was is named Bitchkilla 3.0.
The full name of the strategy, however, is inappropriate in mixed company, therefore, the term '3.0' was born.
Same as pwned.
"Dude, you just got 3.0'd!"
or "Ok, time to 3.0 these suckers."

the third level of law-enforcement - police are known to be the 5-0, security gaurds and bouncers (club security) constitute the 4-0 - whereas the 3-0 represents school teachers or other citizens who are on the look out for people up to no good.

pronounced "three-oh"

derived from the roman numerals xxx, meaning both 30 and porn. came around in the 21st century when members of the GPK needed code words to get past their parents. also makes it more comfortable to talk about porn.
