The sexual act which requires a naked man to lie on his back and roll backwards until his knees are beside his own ears then proceed to masterbate (wack off,beat off,have a bash,have a bat,straddle the yogurt thrower) until he climaxes onto his own face and open mouth.

Eg. MAN1 - man why is the skin on your face so smooth and fresh

MAN2 - I have a grobmuller every day

MAN1 - Sweet.
