sweatpants day

a day in which a person (most often a teenage girl) wears sweatpants, with her hair up, and no make up. these days are most common after a late night, a break up, or paired with a hangover.
it is best to not mess with a girl on these days, she will attack.

Oh no! She's wearing sweat pants. It must be a sweatpants day! Don't mess with her.
