A condition in which
the arches of one's feet are collapsed. It's painful and you have to wear ugly
prescription shoes and you can't run fast or even walk for long periods of time without experiencing utter
agony. Be thankful that you don't have this.
I have flat feet, asshole, that's why I have a fucking
doctor's note to sit out of
PE. Shut the fuck up about things
you don't understand.
