The female counterpart to the Bro. She is sexually promiscuous, wears ugg boots, leggings and a North Face. She gets drunk and shouts things like "I don't give a FUCK who's sleeping!" The term originated from the magnitude of skanks living in the Southwest Residential Area of Umass Amherst. But living in Southwest is neither necessary nor sufficient for someone to be considered a Swesty.

Get the Swestymug. A verb meaning to party like you believe it's the end of an era; similar to the way people partied on New Years in '99 because they thought there would be a massive computer crash.
