Hot girls (generally high schoolers) who have a shit ton of school spirit and are amazing dancers and use pom pons (poms) to make their half time dances even cooler. They also wear cute uniforms.
DO NOT CONFUSE POMS WITH CHEERLEADERS!
*poms have much more talent
GUY: "Look at those sexy poms shakin' it!"
OTHER GUY: "Yeah I'd like to see them without those uniforms on!"
