Also a term used by the "B:\" hacking gang as like "secret handshake".
(Note: the jock usually responds with a "stock" insult IE: "your mum" "fuck you" "you are a idiot" and then slumps off to see his girlfriend, which incidentally have never seen each other in their lives, talked for 10 minutes and are now kissing and hugging)
B:\ Hacker: Pac.
Other hacker (not bdrive): Whaa?
Other B:\ Hacker: *nods discretely*
"Hopefully he'll supply alc for any GP 's in the future"
"He got his fake ID taken away last week. Ugh we lost our best PAC. The pics will suffer"
'Pac' is used to describe anyone close to the gangster lifestyle and knows what it's like living hard, just like Tupac did.
Mostly used in the negative to describe someone with 'no pac' who has lived an easy suburban life with a nice house.
