Plungin in da dungin
When a guy presses his lips against a woman's asshole and forms an air tight seal and extrudes the cum deposit from her anal cavity. You be "PLUNGIN IN DA DUNGIN"
You come home with some dirty whore and she tells you, to suck her pussy - but you rather kiss her ass and go plungin in da dungin and hopefully she won't give you any shit for not sucking her dirty pussy.
