back five 

When someone offers up a high five and you give them the back of your hand instead of the palm. Could also be described as a "half a five."

A team scores and some dude says "high five man!" then as you are giving the high five turn your hand around to give the "back five." Maybe because you want to be cool with that person (not leave them hanging) but you're just not into it - it's like a weak high-five or a half-high-five.

back five 

Simply the same concept of giving a high five but backwards, using your backside of your hand and connecting beautifully with the other individuals back hand.

Back-five 

Backhand someone across the face.

The pimp raised his hand to the hooker and proceeded to back-five her across her face till she was able to pay him the allotted amount of cash.

The back of the pimps hand was sore from giving out so many back-fives.

Back hand five 

It's when your too lazy to turn around or your hands are occupied to give a normal high five so you give a high five with the back hand

Person 1: High Five!
Person 2: I can't I'm carrying my books, but Back Hand Five!
(clap)
