Front potatoes
(noun) While similar to a combination of a FUPA and a muffin top, front potatoes are unique in that they are characterized by the presence of an exceptionally tight belt or tight waistband. This constricting element makes the lower half (the fupa half) rather shapely--as if there's a bag of potatoes in the subject's pants. While generally seen in men, "front potatoes" don't discriminate based on sex.
Michael's fupa was strapped in so tightly, he was rockin' some mad front potatoes.
