pit biker group

Everything was as usual; you were walking with your friend. Evening. You're strolling through the park and see some pit bike riders; they were sitting on the swings next to their bikes, and your friend suddenly joked, "Imagine if they suddenly shout something like 'full throttle, let's get acquainted'!" and you both laughed at that, starting to mimic the 'vroom vroom' of a pit bike. Just as you're passing by and sitting down on a free swing, you suddenly hear them calling out in your direction: "HEY GIRLS, OVER HERE! COME ON, LET'S GET TO KNOW EACH OTHER!" We laughed but walked over. There were four of them. the rest is up to you to decide what to say
