Prep

A noun- A person who goes to a prep school.

A girl that wears knee high socks, sweaters, plaid skirts and buckled shoes. Not to be confused with someone that wears short shorts, brand name t-shirts(or tank-tops), and wears gallons of make-up. This would actually be called a slut, hooker, whore, or popular girl. If someone goes to your school(and your school isn't a prep school) then they are NOT preps.
