Brain Sister

A "Brain Sister" is a girl who wears glasses and finished high school. However, there is some debate as to whether or not a "Brain Sister" actually wears glasses.
"She was only twentyseventeen, she was a lonely beauty queen, she was a brain sister, Texas Instruments all day..."

Quoted from the Limozeen song "Brain Sister"
