Gangs Sticking Together: The Warriors (1979)

A member of a badass girl gang, the Lizzies (we don't make these names up, we just report them), suprises a Warrior during an amorous moment.

Toughs in baseball uniforms and face makeup. Toughs dressed like the Village People. Beautiful lesbian toughettes. And best of all, toughs with switchblades. A rival gang member--on roller skates, if you will believe it--prepares to do battle with the Warriors. On roller skates. Really.

Utilizing the sort of maneuver that works only in movies, a Warrior has thrown his stiletto, knocking the gun from a Bad Guy's hand.
