Use signs--"Enterprise" "Wildcats"
The cheerleaders can say "Enterprise" while the crowd yells "Wildcats"
Do the same for school colors--"Blue" "White"
You can also use signs to spell out the mascot--W I L D C A T S
The old "Defense" sign is cute using a real piece of picket fence cut down to fit the occasion. Hold up a sign that says "D" then hold up the piece of fence. It's a bit corny but people love it!

i know a cheer that goes like this:
when we say GO, say GO ___ (team name or mascot), GO, GO _____
