The other definition is utterly wrong. Here is a correct interpretation of a prep guy.

1. During the summer he is found in Nantucket or the Vineyard.
2. He wears Ralph Lauren, Lacoste, LL Bean, J Crew etc.
3. He wears mocs and beige trousers and pastel-colored poloshirts.
4. He's educated. Few are jerks. He's cultured.

He DOESN'T wear A&F, AE, Hollister, Old Navy, Aeropostale or any of those other "mall" stores

A prep guy isn't the jock who dates "cheerleaders" in high

school... he goes to a prep school in new england (Deerfield, Choate, Hotchkinss...etc.)
