fratjocks 

The best of the best on campus. The Fratjocks fuck the puny Pledge Boys on their 450 foot yacht. Grant Macdonald is very fond of the fratjocks and even on occasion invited them to the cockship.

Boy-“bro the fratjocks are fucking the pledge boys in the showers right now!”
Girl-“Well the fratjocks are just that cool I guess.”
