My two favorites from when my 6 year old was cheering last year were these,

Open up the barn doors..kick out the Hay! (Swinging arms wide before
dropping and kicking their pom poms with one foot)
We are the girls from the ARA! (Arm movements to form A R A)
Turn on the radio and what do you hear? (Movements to fit)
Britney Spears doing a cheer!
You gotta F...I...G.H.T!
You gotta F...I...G.H.T!
You gotta F...I...G.H.T!
FIGHT FIGHT FIGHT for Victory!

Totally, for sure!
I just got my manicure.(holding out fingers as if wet)
The sun, I swear!
It's bleaching out my gorgeous hair. (Running hands down hair)
33 to 44, (holding up 3 then 4 fingers)
I don't know that silly score! (Flapping hand)
Go go! Fight fight! (fist pumping)
Gee I hope I look all right! (brushing away invisible lint)

I would love to know that these too cute cheers are moving beyond the ARA
borders!
Have a great day,
Kerri
