Tangy Curtis 

a sexual move performed on a woman, where the hand is sent down the backside of a woman with a tuck and curl motion as it approaches the bumhole or the beaver and the middle and index fingers do the probing

Variation - Tango Curtis (origin: Buenos Aires) same as above, finishing with a spining motion upon probing

Man, that chick hit the roof when I slipped her the Tangy Curtis!

Tangy Curtis 

The best thing a man can do for his woman...or anyone in a sexual relationship that feels the need to probe further into their relationship

Like a tornado in the tush
