Abbreviation for the Western Athletic Conference, a collegiate athletic conference in the United States comprised of (as of 2009), Boise State, Fresno State, University of Hawaii, University of Idaho, Louisiana Tech, University of Nevada, New Mexico State, San Jose State, and Utah State.

Formed as a power conference in 1962, all six of its founding members are now members of either the PAC-10 or the Mountain West Conference. Current membership has been relatively stable since 1996, with the top portion of the WAC dominating the national college scene, with the Boise State Broncos and Hawai'i Warriors gaining national football recognition, while the Nevada Wolfpack, Utah State Aggies, and New Mexico State Aggies have been doing the same with NCAA Division I Basketball.

Nicknames for all sports teams are, respectively, the Boise State Broncos, Fresno State Bulldogs, Hawaii Warriors, Idaho Vandals, Louisiana Tech Bulldogs, Nevada Wolfpack, New Mexico State Aggies, San Jose Spartans, and Utah State Aggies.

Hillbilly Hank: Gawrsh, I'm lookin' et our football skedyool, and we play a buncha weak-ass opponents AGAIN this year afore our SEC conference games start!

Moonshine Matt: Slow your roll, Henry, my old chum. If you'll notice, we do appear to be playing Boise State next month, and I daresay they scare the bejeezus right out of my nethers. Whilst the bottom portion of the WAC scares no one, the top half is capable of toppling even the mightest of egos, nawmsayin'?

Short for Washington College, a place where public nudity is accepted and parties are in no short supply. Greek life is in constant trouble with hazing, and sports are non-existent, save for lacrosse. Drugs are casual, as is sex, the walk of shame, and an infamous reputation-expected with a college smaller than most high schools. Teachers often throw parties for the students, and there is an annual Birthday Ball where everyone gets hammered together.
WAC is a small school with a big hazing/partying problem
