Sunny Sweeney's definitions
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.
