Mid twenties males who work all year as waiters or managers of small retail stores to afford a one week vacation in Cancun every Spring break. PSBs can be identified by their muscles, barbed wire tattoos, spiked haircuts, backpacks, board-shorts, and the ever-present can of Natural Ice beer in hand. PSBs are loud and like to high-five their "brahs" when they do something in front of females that most other people would consider rude or embarassing.
PSB's are subclassified as PSB cat 1 (category 1), cat 2 (category 2), and cat 3 (category 3).
Most PSBs attended Syracuse University and majored in accounting.
Man, you're a friggin' PSB!
What bro? PS-what? Yo dog, let's go scam on that ho...Hey ho!
