slang for a 30 pack of beer. Only used by Southern Californian beach bums who in an effort to sound edgy, tried to coin their own phrase similar to an existing one for the same thing. (see 30-pack) But lets be honest Southern California has given us worse (see the hills)
"Whoa bra I got high, past out and was raped by a sea lion, want to go halvsies on a thirty-Rack?"
