Muffintopism 

The new fashion craze sweeping poverty stricken cities worldwide, where young women who make babies end up in a welfare induced state, wearing the undersized clothes they have left over from their promiscuous, childless, highschool days. The result being that their gut fat is squeezed downwards to their pant line, where it becomes sandwiched between two tight areas resulting in protrusion. A process very similar to the formation of mountains between continental plates.

"MY GOD... Muffintopism has taken over our city! Get the president and Jenny Craig on speed dial!"

muffintops 

The part upper part of the buttocks that are exposed when wearing low riding jeans or pants.

When these fat chicks wear pants too tight and their ass gets pushed up out the top of the waist band.

Yo, your muffintops are showing.
