BEAT HOOVES!

An exclamatory order that compares a woman to a ungulate mammal (that which has hooves, such as a pig or a cow) while asking her to evacuate the premises so rapidly that it sounds like she's beating her hooves upon the ground.

Situation: A fat heifer comes up to a guy and asks him to Facebook her.

His reply would be:

BEAT HOOVES! (BITCH)!
