when a thin armed, skinny legged woman has a bulge in the middle of her stomach--ie a pouch like a kangaroo would have. this women seems to acquire an average looking body until you view their abdomen--a bulge of fat.
Mike: shes average, the one over at the bar sitting down.
(woman stands up)
Fred: eww dude shes sporting a pouch!
Mike: damn those pouches!
(mike starts sobbing)
Fred: it'll be okay buddy
(patting Mike on the back)
Fred: if she did some crunches, that pouch would be nonexistent..i think...
(mike continues to cry even harder)
