Its what Tupac's character says in Juice (1992) when he caps another hoodie under a bridge. Side note: one of Tupac's best performances, on screen or off. Wayne Brady totally copied him on the Chappelle Show.
Tupac: "Riverside, motherfucker"

An early manifestation of cougars (see UD definition). Usually applies to very late twenties and early thirties women who are desperate for a mate since all their girlfriends have just gotten married. They often appear like fun party girls, at first, but then reveal their true desperate, land-a-man motives. Be wary.
