A term coined by "The Todd," a perverted character on the hit tv comedy "Scrubs."

To interpret a slap on the face as a misplaced high-five.
1:
Carla: Why is my stapler on the floor?
She bends over to retrieve it, revealing a slight peeping thong.
Todd: Thonnnnnnnng!
Carla whips around and slaps him.
Todd: Face-five! Oh, yeah!

2:
I tried to look up that chick's skirt and she gave me a face five for effort!

When you say hi five to someone but they wont return it so you slap them round the face.
Dude 1: That was awesome!!! High Five! (dude raises his hand)

Dude 2: Are you like 10?

Dude 1: Face Five! (dude slaps him round the face)
