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.
Carla: Why is my stapler on the floor?
She bends over to retrieve it, revealing a slight peeping thong
Carla whips around and slaps him.
Todd: Face-five! Oh, yeah!
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)
To high five someone's face, usually very hard.
Guy: Oh dude woah yeah
Other guy: Totally, facefive!
I totally gave that guy a facefive.
Slapping someone across the face.
Guy 1: "Ow dude, wtf
?! You slapped me!"
Guy 2: "No I didn't, I face-fived you
To intentionally miss someone's hand during a hi-five and smack them on the face instead.
I gave this one idiot a face-five the other day, it was totally sweet.
