a term for a disliked university adminsitrator. A reference to Larry Moneta of Duke University (formerly University of Pennsylvania) who was an administrator involved with bringing disciplinary action against a student who called a group of students a 'bunch of water buffaloes.'
That guy is so useless, he's such a waste, what a water buffalo.
A water buffalo is a very obese person on a team. Instead of running with everyone elese, he/she spends their time sitting on the sidelines drinking all of the team water.
Player 1: "Hey, look at Billy, hes just sitting there drinking all of the water"
Player 2: "Yeah, he is a water buffalo."
