Tennesee Tickler
This is when you are have sex with a woman from behind doggy style and when she is about ready to orgasm you start tickling the back of her knee, thus her losing concentration and providing her with a better orgasm.
As I was getting banged from behind, he started tickling my knee and as I turned around to ask him what the f*ck, I had the best orgasm I've ever had! He just smiled and told me it was the Tennesee Tickler!
