Originated in Tony Danza's mythic early days as a porn star. His signature move was said to be a mushroom welt (cockslap), during which he'd shout out his surname.
aight sometimes when a girls giving you head she'll ask you to let her know when you're gonna cum so you dont cum in her mouth. well a danza dunk is when you're about to blow it and you hold her head down while yelling "Who's the boss?!"
she told me she wouldnt swallow my load so i danza dunked her ass
When you are giving it to a chick from behind, you yell out "Who's the boss?" She'll get confused, turn her head around, at this moment, you donkey punch her in the face and then scream TONY DANZA!!!
Oh man, I totally pwnedJeff's girlfriend last week when I gave her a Tony Danza.
