When you got a well rounded sag going on and some of your boxers start getting hitched up and fluff out over your pant line. Soon your shirt unknowingly is caught above this fluff of Fruit of the Loom and before you know it you got yourself a Grade A Premium Diaper Sag.
Dude, i used to think that kid was fucking legit sporting that natural sagall day every day. That was until i saw him DIAPER SAGGING all the way to class today. Doesn't he know a natty sag should be accompanied by boxer briefs? All he's gonna get with that is some nasty slam hogs. DEEEEEGEEEENENNNNNNNN
