The state that a girl's feet look like after a frat party, ie covered in dirt/beer and whatever else was on that floor.

happens mainly when you wear flip flops or sandals
Sunday morning:
girl 1: oh my god... your feet are absolutely disgusting!
girl 2: Yours look the same! i guess frat feet just happen.
