Almost synonymous with cockblock, but worse. Someone who constantly thwarts sexual encounters out of jealousy because they have no game. Can single-handedly ruin a party unless immediatelykicked out.
The two part act of sucking semen out of the anus with a straw while maintaining enough of a vacuum to get the greasy, and sometimes chunky duckbutter that runs along the taint.
Being careful not to miss a drop, and priding himself as a pro at Felching For Duckbutter, Gabe Athouse aimed his straw and inhaled every last drop of the load he left as well as the grimy, nutsack buildup.
A dustbuster is an alpha male who, similar to the powerful vacuum of the same name, literally busts the dust by removing "dusters" from women they are mistreating or have no business being with. Dusters, who are hockey players that sit on the bench and collect dust, are removed to the trash and replaced in their prior relationship by the dustbuster, a more skilled male with a bigger cock who treats women with respect.
Tommy is such a fucking duster. He sits on the bench every game collecting dust and treats his girl like shit. Thank God the dustbuster busted the dust. It was horrible to see such a beautiful woman mistreated by a duster.
