This dance is always played as the last number at Homecoming, Prom, or etc. It's cue starts when Mr. Daas sings "Freshmen! Sophomores!" in the Berkley Rally Song. At that point, you hit your pelvis region and then throw your hands in the air and make a 'lasso' motion.
In order to perform this dance, everyone MUST be wearing eyeliner and have their hair in a perm.
