You were part of the Rodents biker gang (Butchy, Lela, CheeChee, Lugnut, Struts. Butchy and Lela are siblings). They were constantly trying to take the grill, Big Mommas, from the surfers (Tanner, Giggles, Seacat, Rascal and more). You had all just walked in, all the bikers dressed in leather. You and the other girls had one shorts and tied crop tops (time period looking to the sixties ofc) with leather jackets over them. Some in heels some in heeled boots. The guys were mostly in jeans and leather.

them and all the surfers started arguing until the bikers started dancing and singing (musical duh) and Brady had joined along since he knew the movie like the back of his hand (you guys didn't know it was a movie. You just saw it as life). Mack (girl) was watching silently from the side

the juke box pauses and everyone stops taking a few breaths as Brady runs a hand through his hair before he hits the juke box and the song continues

Everyone; "Don't stop, stop the music. We ride fast like bullets. We do anything we want, anytime we want oooh yea. Oooh yea. We just ride, ride, ride all day. We're not gonna live any other way, oh no we're not gonna live any other way~"

You and the other bikers (+ Brady) danced and sung while the surfers watched silently from the side
