look up any word, like wyd:
The act of slapping someone in the face with one's penis. Both a noun and a verb.
I woke her up with an alligator slap.

An open-handed alternative to the Donkey Punch.

If administered properly, the Alligator Slap has the same anus-tightening effect as the Donkey Punch, but allows the sexual partner to remain conscious during ejaculation.
I wanted to see the look in my girlfriends eyes, so I gave her the Alligator Slap instead of the Donkey Punch.
