This was originally sourced from one of the best groups of Counter-Strike players - their team's name was 'SK'. The name progressed into becoming an insult against gamers.

Eventually, it came to mean 'sh*t kunt' and can be used as an insult in many situations.
1) 1337 Gamer: U suk, u SK!

2) (Person falls over) Bully: Look at him, he's such an SK!

Short for Sigma Kappa. The greatest sorority out there. Always classy, never trashy; these girls are the ones that dropped your tacky ass during rush.
I wanted to be an SK but I had to settle for DG.

SK is an abbreviation, which stands for Script Kiddie, the infamous group of hacker wannabes and the like that have to use real hackers' discoveries and knowledge to affect a system/network/website etc. rather than use their own.
The SKs used what <hacker> had discovered, and took the network down.

Damnit! Some stupid SK's got a DoS attack tool and DoS-ed my site!
