Gunt-Button

is a second navel formed in the pelvic region of men by an overabundance of fat depositing in the areas surrounding the genitals causing the penis to become engulfed in a layer of fat.

That guy's so fat, he's gotta use a q-tip to clean out his gunt-button.

Friend: "Dude, check out that guys nasty gunt!"

You: "No man, that guys got a dick; he has a gunt-button."
