There's no Polish dictionary around here, nor do I think they're consulting for their "shoes." Rather it should be a Spanishization of English booty, which should not be for the "prize, loot" but for the slang for "ass, buttocks", almost always feminine and that is extended to the vulva, the vagina and in an extreme synecdoque to the woman as a sexual object. In any case, it does not exist in Spanish. See English/booty .
