Very similar to a gunt, a pronounced bulge starting at the belt or rim of the pants, with the crotch area of the pants protruding outwards, creating a disgusting melon shape. Again, not quite a gut, not quite a cunt.
A gunt causes tremendous wardrobe problems. If she is not careful, she's going to give herself a twattermelon.

That is repulsive.
