Close to the idea of a moose knuckle or a camel toe. The only difference is that the woman is really fat and she wears tight pants and you can see the cellulite through them, looking very similar to a sponge.
I was walking down main on a Friday night. Bitch had white yoga pants on and you could totally see her sponge knuckle.
