A good crowd cheer is:
"If you want to win you've got to yell with all your might
When we say red, you say white
RED
WHITE
RED
WHITE
RED RED
WHITE WHITE
If you want to win you've got to yell with all your might
When we say go, you say fight
GO
FIGHT
GO
FIGHT
GO GO
FIGHT FIGHT

x2
GO GO
FIGHT FIGHT
WIN TONIGHT"
It's really cute :) All they do is clap on beat and do any arm movements.

As for a routine...put a lot of motions and ripples in it. Put a basket toss and some stunts at the end. Some good songs are Boom Boom Pow by Black Eyed Peas; Popular by The Veronicas. Anything fast paced or you could download some cheer mixes

i like tht cheer i will tell my coach to use this website
