Filthy SkeeBall 

Sexual act, while having sex in the missionary position. Right before ejaculation, the man pulls out, shoots his load in her belly-button, then punches her in the stomach trying to shoot the cum into her mouth or on her tits, gaining points for nipples, eyes, and mouth.

Billy was banging some chick and got 50 points when he performed a filthy skeeball.
