Its a natural thing that all boys and men get particularly when they're teenagers. Just try to calm yourself down when it gets like that :P and try and wear baggy trousers so it doesn't notice.
I have seen kids as little as 9 saying fuck, and when they do, they usually say it out of any context, and repetitively. Also, I think, although it sounds fake, it could be real.
(but the "hey boys and girls" part kinda gives it away that this is fake)
