ORIGIN

Created by Justin and Mike during a trip to Ohio in July of 2005.

Al Capone was a notorious gangster from the 1920s. A legendary force to be reckoned with. Look him up and you might start to understand why getting Al Capwned is such a huge beat down. Hehe.
(In reference to a computer-played terrorist sneaking up on a crouched human player and blowing the crap out of him/her execution style): "Dude, you just got Al Capwned!!"
