Used to refer to the girls of Presentation High School in Willow Glen, CA. Presbians are typically sluts that get around a lot with both sexes (emphasis on the both). Presbians will often engage in sexual acts during school hours in the bathrooms and otherwise. Bellarmine boys like to hook up with Presbians but will always end up taking a Notre Dame girl to meet their mother. Presbians have a tendency to dress in an identical manner to mixers.
See that Presbian over there in the pink shirt and matching knee socks sucking face?
Which one? There are so many!
