Get the Battersea Slam Dunkmug. The act of having sex with a guy who is an athletic. He scores extra points since he is extra sexy and attractive. Since he is an athlete, the term slam dunk is a perfect point, because the sex is on point.
Aarod was a slam dunk, I knew it when he played ball and scored a perfect pointer. After the game ended he scored a slam dunk with his wife.
