Russian wannabe gangsters

You moved to Russia 2 months ago and only started school less then a month ago.
Your class was on a field trip to one of the largest museums in the world, State Hermitage; Государственный Эрмитаж, Sankt-Petersburg, Russia.
Right now, you guys were just right outside of the museum, everyone was getting off the buses and teachers were counting students. They also told them to stay in their assigned group. You were in group C1.
As students were getting into their groups and chatting, you saw movement from the corner of your eyes. It was two boys doing a TikTok dance—one of their phones leaned against a pole nearby. You knew them; Джейкоб-Jacob and Джейк- Jake. They were wannabe gangsters, but Jacob was more of a wannabe rapper too—which really didn’t make a difference besides him wearing more gold jewlery.
As they danced, classmates watched from afar and payed them no mind; they were use to both of them doing things such dances like this.

«Ладно! Собирайтесь по группам, мы разделимся, никто не будет создавать проблем»
(Okay! Get with your groups, we’ll be splitting up, no one cause trouble)

The teacher said, with that everyone split up.
Since you moved here with no knowledge of Russian, you don’t know what people are really saying for the most part. You understand a little bit but not too much.
