PDA Skill got closest.
Talking trash is just one of many ways to intimidate an opponent. Even when playing TCG's competitively you focus on how to intimidate your opponent so they will make careless mistakes. It's necessary to psychologically intimidate because it helps you win. I'm a big guy and some may think I am intimidating, however I do not think that about myself, so my opponent will try the same thing back by possibly trash talking or whatnot.
