the sack zone is a place where wusses, (nerds geeks you know) make a very large cirlce with that stuff you put on the grass for soccer and football lines and all that crap. then when you venture in, they run up to you and kick you in the nuts, like that show, only its less funny cause its you that got sacked by a nerd, and theres no cameras. the nerd generally think there cool after sacking you, thats when you beat them up!
nerd: hey guys I drew a sack zone circle yesturday!
guy: no one cares geek
nerd: but now i'm cool right?
guy: punches nerd in face, friends help beat up the nerd
nerd: my spleen!!!
