Wear burnt orange to the game. Cuss a lot, _____ and moan about there not being a rivalry, and then leave early. Throw tortillas every time your team gets a first down, and randomly yell, "Get your guns up!" If someone is in front of you while you wait for concessions, reach deep down from your gut and let out a hearty, "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh Sic 'em".
Should you find your team behind near games' end, then prepare yourself to sprint onto the field yelling, "This field is not a memorial!!!!"
Enjoy your stay.
