1.
VLO
A term meaning "Valley Locals Only" that originated around late 2003 from a group of Malibu High School freshmen in politely sarcastic response to the local "gang" MLO, or Malibu Locals Only. It is used as a joke amongst some non-Malibu residents who attend MHS.
Malibu Local: VLO? MLO, bitches! What, what! We gone drive 'round in our Range Rovers an' seriously tear up any punk-ass-tight-pants Vals who gone step they faggoty-ass shoes all up on our beaches, nigga! Hooty-hoo!

non-Malibu Local: ... Wait, what?
