I mainly play SWAT, and I don't really troll.
Unless I've been trolled.
When someone yoinks me for instance, I usually start following them around jacking their kills. Or yoinking them. Or shooting them 4 times and loling as they get 2 shot.
Or if they try to yoink me and end up getting me, I ALWAYS go for the kick. Always. In SWAT, it is not a detriment to have fewer teammates, so having one less **** as a teammate is totally worth being outnumbered.
