Most annoying players in CS GO

If you play CS GO then you problably have seen players who are nice and fucking annoying players. There are different types of annoying players.

1. Very young kids.
   Sometimes young kids can be nice in CS GO but most of the times they are just fucking screaming at everyone If they dont like someone.

2. Russians.
   Usually i have atleast 1 russian in every match i play and they are also fucking annoying because i cant understand their language and then they are screaming at me why i dont speak russian and they sometimes think they are the best.

3. Players who think that they are the best players.
   Usually players who think they are the best their favourite word to screaming is of course "NOOB" but If you look their score then they usually are at the bottom.
