Glad to my man. Mind you the high majority of these are indeed real, but I like to throw comedy around in my life. So some are quite funny. Even some of the actual ones I cheesed up a little.
Arizona State- Pitchfork (simply the peace sign with the pinky extended, for those that are slang-knowledgeable, it is the Shocker)
Baylor- Bear Claw (extending all fingers and slightly bending them)
Colorado- Buffalo Horns (identical to Hook Em)
Florida- Gator Chomp (extending the arms, widening them, and bringing them together in a chomping motion)
Florida State- Tomahawk (extending and bending the arm, usually the right arm, at the elbow. Mostly to the tune of the overplayed Warchant.)
Houston- Cougar Paw (similar to ASU's Pitchfork, but with the extended fingers bent)
Miami- The U (raising both hands, with the thumbs making mirrored "L" shapes and touching)
NC State- The Wolf (similar to Hook Em, but with the middle and ring fingers extended outward and touching the thumb, forming a "wolf's head". In the game, the player separates the finger combo from the thumb multiple times, mimicking a "barking" motion)
TCU- Frog Horns (identical to the Cougar Paw at Houston)
Tennessee- UT (extending the arms nearly into a touchdown signal "U", then lowering them to a horizontal position, "T". For those familiar with the man, Terrell Owens formerly did a celebration similar to this, starting with the "T", then raising his arms above his head to form an "O".)
Texas- Hook Em (We're all college football fans here, no need to go into detail. But for the occasional new guy, it is a closed fist with the index and pinky finger extended.)
Texas A&M- Gig Em (an over-glorified thumbs up)
Texas Tech- Guns Up (forming a gun shape with the index finger and thumb. It's wrong in the game, as the player doesn't extend the thumb.)
UCF- UCF signal (extended arms form the U, then lower the arms into a "C", a la YMCA, then lower the upper arm into the shape of an F)
USC- Victory (a highly excited peace sign, to the tune of Fight On, which coincidentally is played every seven seconds, score or not.)
USF- Bull Horns (identical to Hook Em)
Edit: There are more that were left out of the game, I'll include them (more or less fan motions).
Kansas- Wave the Wheat (fans raise their arms, extend the fingers, and sway back and forth, alternating rows. I.e. Row 1 starts left, Row 2 starts right, etc.)
Michigan- Tears of Sorrow (this tradition must have just started recently, but sometimes when I watch UM games, during the 4th Quarter, the fans are in their seats with their faces buried in their hands.)
Ohio State- The O (all the fans extend their arms over their head and form an O)
Oklahoma State- Guns Up, Wave the Wheat, etc. (sadly they can't come up with their own traditions)
SMU- Pony Up (simply a peace sign with the fingers bent)
Utah- The Mighty U (similar to Miami's U, but only involving the index finger and thumb, instead of all fingers)
UTEP- The Pick-Axe (both hands in a fist, thumbs extended. Touch the hands at the pinky sides. Make sure the arms are touching all the way from the pinky knuckles to the elbows. Word to the wise, if you're fat like me, don't try this. You're elbows won't touch, and if you are around people, they will get a good laugh at your expense. And kudos to all of you that actually tried to do this.)
