Game: Quake, Doom, Team Fortress 2 Telefragging is timeless troll technique that's been around since the good old days of multiplayer shooting. In some FPS games, if you spawn at a portal while someone else is there, it's possible to kill an enemy (or friend) and turn them into an exploding firework of blood. The mechanic was originally introduced to cope with the possibility of two characters paradoxically occupying the same place, resulting in this hilariously fun way of blowing up opponents. In Quake, nothing was worse than being at full health, chasing someone you knew needed just one bullet to end their life, only to turn into red vapour thanks to a well timed portal jump.
