The wet slap 

When a girl gives a hand-job to a guy and then slaps his face with his cum still in her hand, spreading it all over his face - as a part of women's retaliation for all the nasty sexual things men do to them so they can tell their friends later (or write about it on urban dictionary...).

"He acted like such a douche last night I had to wet-slap him. He got the wet slap alright."

"Girl, I can't believe you just wet-slapped me!"

Slap with the Wet Glove

When a man, after intercourse, removes the used condom ("wet glove") and smacks his partner across the face with it.

After Kurt and I finished last night, he gave me a slap with the wet glove. I wasn't sure how to feel about it.
