yes, but that's generalised...we don't specifically speak ill about someone in particular from someone's family...and I personally do not use the mc and bc slangs...My personal faves are a-hole, degen...and a slang called "bokach***"...
Depends if I'm on my main or not. If yes, I trashtalk softly, if not, god have mercy I'm bout to wish the other person's whole family tree to go extinct
when i trashtalk i only criticize the opponent playstyle, because i get so tilted playing this game. besides that, i am a cool person, never trashtalk anyone
