thigh five 

The slapping sound that is made during sex when the two participants' thighs slam into each other

Dude you and Jenna were having so much sex last night.

No we weren't!

Yes you were! I heard at least ten thigh fives come from your room!

A thigh five is a greeting or a salutation extended between two women (or men...if you're so inclined or daring due to proximity of junk) by gently slapping right inner to the other person's right inner thigh with the same pressure as a standard high five!

Me and Bonnie, who I hadn't seen in a long time, gave each other a "thigh five" upon being back together again.

Thigh five 

The urge to put your hand between an attractive woman’s legs (thighs) and move it back and forth in a “slapping” motion.

Look at that girl over there; boy, I sure would like to give her a thigh five.
