players being whiney little bitches. thinking that being an annoying cunt is cool. being bitches about stats/elo/winning/losing. acting like the kind of people you would be embarrassed to know. being completely ignorant of facts/reality
quake was kinda the last bastion of hope for me. started playing again recently only to learn that the same scum i want to get away from are playing this too :(
you are right though, it's not just trash talk, it's being REALLY obnoxious to everyone all the time, thinking they are being part of the cool kids somehow. It does include kick spamming etc. just pissing everyone off.
The ones i met seems to be newschool british kids, not to say they are the only ones.
even before qlranks came about, you had people who would be somewhat obsessed with sv_skillrating, but now that qlranks is known by most of the community, it brings out the worst in a lot of people :/
