14.
A short, constantly drunk 20somethingyearold who lives in Austin, TX. When he is not playing in one of his 9080948 local hardcore bands, you will likely run across him terrorizing hipster/fratboy keg parties with his friends, at which time he will be chanting, slurring, or yelling in a distinct southern drawl which only emerges in the ominous presence of alcohol. Be warned, the only intelligible words out of his mouth will be "FUCK", "YO", "DUDE(S)", "RAGE", or "FAGGOT". Foster goes to community college, is an adamant Bush supporter, still lives with his parents, and consumes superhuman quantities of various pills and PBR. he has also been reffered to by the community at large as a "Misunderstood Local Hero" due to his well-meaning but drunken antics.
Foster: "fuuuuckkkk youuuuu faggggotttt!!!!"
or
"yoooo dude lets fuckin raaaaage!!!!"
or
"4 more years!!!! troop surge motherfucker!!!"
or
"GIMMEEEE A BEEEER"
