Refers to a sex position where the broad is resting on the top of her back/neck and her ass and cooter is pointed towards the sky. The man then stands over the broad, points his plunger downwards and dunks his beef into her clam. This scintillating sex position can be turned into the “Drummer Boy Plunger Dunk” by simply beating that ass like a bongo.
see the definition....if you can't figure the Plunger Dunk out then you are to stupid for sex.
