The large hump of putrid fat that sits just above the female vagina, in some cases this may need lifting up to belly button level in order to complete such bodily functions as urinating and sexual intercourse. This hump is especially disturbing to those who gaze upon it if the female in question is wearing tight trousers, such as yoga pants, or a mini skirt.
"So I took this girl home the other day and had to strap a belt around her fanny fat so I could get to her pussy."
