Two girls residing in Southern California embraced the name grundle (slang for taint) after a group of people constantly called them it and now refer to themselves as the grundle bundle because there is more than one of them. They are often characterized by their oversized, overworked vaginas, rotten jack Daniels loving livers, brittle bleached hair, and their constant need to try fighting people. When within a mile of them you are likely to smell cat feces and abortion discharge.
Did those girls have names? No, they just go by grundle bundle.
Do those girls know what they're saying when they refer to themselves as grundles? They don't care because they're the grundle bundle.
