MAB
Middle Age Butt. A phenomenon in which a woman's ass explodes in size dramatically, over a short period of time. This specific type of enlarged butt can be identified as being much longer vertically than it is wide. Commonly found strapped into dime store-caliber jeans such as Riders, with the waist pulled up high above the belly button. Seen from the profile angle, MAB will not curve out sexily like a badunkadunk, it will lay flat and tall along the back. Also known as mom-butt and mom jeans. It should be noted that the wearing of mom jeans can also be the sole cause of front butt (a butt in the front, below the belly button.)

"mabs" is an acronym for Mid Afternoon Butt Sweats. The mabs is that moist, slightly unpleasant feeling in your underwear on a warm day or after some physical activity.
"mabs" is frequently preceeded by "the" ("the mabs").
