look up any word, like swag:
1) The preppiest preppster around. One who dresses uniquely southern, and is classy as hell.

2) PSMs are often seen in Ivy League schools, Fraternity/Sorority houses, or at their local country club or yacht club.
Bro, did you see that Prep Star Millionaire at the party last night?

Yea, bow-tie and all.
