Noun. /sluht-buk-et/ A girl who likes to have sex with multiple partners and lets them cum in all three of her orifices; pussy, ass and mouth as many times as they like. Her holes act as a receptacle or “bucket” for the mens’ semen, thus making all three of her holes “buckets.” The combination of a slut that lets men use her holes as cum receptacles is a slutbucket.
to dump someone that you were just hooking up with and not even actually dating. Usually done through an unceremonious medium like a text mesage or Facebook chat.
"I got a text from him this morningsaying it was over."
"What, weren't you just hooking up?"
"Yup. I got slutdumped."
