Bruck-Back
noun
Prominent Backside;
Jamaican influence term for a curvy girl with a large, prominent behind, often sexualised. In UK dancehall, bashment and grime settings it can be playful, complimentary, or crude depending on tone, focusing on physical shape rather than personality. “Bruck-back gyal” refers to a woman who can “break her back” during sex, (arch her back dramatically).
