The trashy, lowerslung cousin of the hipster pant, favoured by female fashion victims, often those born without the ability to realistically determine their size. Although there is no agreed max-min amount of bumcrack to be shown, a visable 'brickies grin' is a key factor in determining whether the pant is a member of the bumster family.
OMFG. I'm loving myself sick in these bumsters.

We would always get to see the bumsters whenever we went to a U of I game.
