Bob Fosse

A sex act, where the male pulls out and cums in his hand, then rubs his hands together.
Then rubs the cum soaked hands on the girls face calling her "Mammy".
Aka Jizz Hands.
Bonus if you sing it.

"Dude, gave my girlfriend a Bob Fosse last night"
"Bruh?"
"Yeah, she's one nasty bitch, she loves it"
