muffin bum

you know the fashion where the guys wear their jeans low? well, if a guy wears them mid-butt and theyre too tight he'll end up with a muffin bum (ie his upper bum overlaps the trousers). a real turn-off...

guys, before playing basketball, make sure you dont have a muffin bum!! its disgusting to watch!!

girl one: oh my god! look at that guy! he has a muffin bum!

girl two: euugh!! gross!! shield your innocent eyes!
