The female equivalent to a bro. Often classified by teased blonde hair, oversized bag, abnormally orange skin, often found wearing matching velour jogging sets (while not jogging), and overly large sunglasses. Often found squealing at Frat boys with a drink in one hand and a camera in the other. They can be found in bulk at Frat parties, tanning salons, and Palm Walk. Most likely they will travel in gangs of 6 or more.
"Hey bro, is that a Frat Rat?"
"No, it's just a broweena"
