Muffintop?

This is great I heard this saying for the first time today courtesy of Elvis Duran of the Z morning zoo... (God I miss Howard), evidently this is in reference to when a girl wears low rise jeans and a midriff shirt but doesn't really have the body to pull it off (aka every spanish girl in Brooklyn by my assessment) and the result is a layer of fat protruding from the outfit that looks something like a muffintop. Man what will we think of next?

P.S. In case you're like me, and I pray to God you aren't... you might have been wondering what skinny white guy that sings like a black guy (aka Ricky Astley) is up to... well if you are check this out http://www.thebubbleburst.co.uk/bb.php?entry=Rick%20Astley
