Fullin
A large, shapely, or attractive backside. (This term is a Dominican phonetic adaptation of the English phrase full jeans, which local lore says originated during the US military occupation when soldiers commented on how well Dominican women filled out their denim pants).
American: That girl has full jeans. Dominican: What did you say? That she has a massive fullin? Yeah, I was looking at that too.
