when a man is engaging in sexual and/or anal intercourse (with a woman preferably) one must strike the recipient with an open or closed fist with much force and simultaneously yell "Who's the Boss?" To which the recipient will no doubt answer "You are!" And one loudly replies "No, Bitch, Tony Danza's the Boss!" (Optional: a second strike may or may not accompany this correction)

Similar to the "donkey punch" where a sharp blow is delivered to the back of a woman's head during anal intercourse to relax the anus but at the moment of impact the phrase "Who's The BOSS??" is yelled.
Son, when I get home I'm gonna give your mother a Tony Danza to warm me up for the Hummer your gramdma promised me.
