A prep is a person who's favorite words are usually like, omg, totally, and any other valley girl word that they can come up with. Their favorite color is generally pink, and they love to shop at American Eagle, Abercrombie and Fitch, and Hollister, or even sometimes Anchor Blue. The percentage of preps that are posers is about 50%. They are usually skinny blondes, with an occasional brunette. Preps tend to date jocks, and vise versa. Most of the time, preps are cheerleaders, on the dance team, and spend every day talking on the phone for 4 hours to their boyfriend of the week. Preps are not always sluts, but a lot of the times they are. Preps generally idolize Jessica Simpson, Hilary Duff, and consider Avril Lavigne 'too goth for them'. Preps usually have rich daddys, and have some type of small dog.

2. Look at that chick in the pink American Eagle shirt, she must be a prep.
