gut crack 

The opposite of “butt crack.” Where a person with a large gut wears a shirt that is either too small, or purposely wears a top to expose their mid drift while ignoring the fact that they don’t sport a “six pack” set of abs. Instead, it’s obvious to everyone but them, that they’ve drank one too many six packs and should either hit the gym or buy a shirt that fits.

Look at the gut crack on that chick!
