acronym for: Slutty New Outfit Day
This is when
attractive girls wear outfits that are very slutty on the first good day of spring. They are often found walking in malls or general shopping areas.
Sometimes the girls are very ugly, causing this event to be unwanted or obscene.
Jim: hey

over there; she's wearing a short skirt, thong, and barely any shirt!
George: wow, i didn't think that was legal.
Jim: That would be a SNOD.
Britney Spears dresses like everyday is a SNOD!
