pit biker group

Everything was as usual, you were walking with a friend. It was evening. You were walking through the park and saw some pit bikers sitting on a swing next to their pit bikes, and your friend suddenly joked, "Imagine if they were to yell something like, 'Gaz, get acquainted!'" You laughed and started making gestures like, "Brim, brim, pit bike!" And so you were walking past and sitting on a free swing, when suddenly you heard them shout in your direction, "HEY, GIRLS, COME HERE, LET'S MEET EACH OTHER!" We laughed but walked over. There were four of them , and then it was up to you to decide what to say.
