Shamu

The act of when your girl is riding you in the reverse cowgirl position, you suddenly reach up behind her back, grab her pony tail, and then yank her down backwards in fast and forceful manner. Then, as if to be splashed by water, you cum in her face.
Man my girlfriend has been messing around on me, so last night I pulled the Shamu on her.

Shamu

The large girl at a bar or club that dances like she is the front runner for "So You Think You Can Dance" and hogs the dance floor or jumps up on the bar or table dancing like a trashy individual, but thinks she is God's gift to mankind.

Also the Killer whales at Sea World, but in a nightlife context refer to above definition.
Nick was cornered and tortured last night at the bar by that Shamu.
