lag boosting
When you're in a game like Halo or Warcraft and you get killed because the other player had lag boosting and you were like oh my god this is unfair and you want to punch them.
"Bro, you got me with lag boosting? I was about to kill you!", @HaloPlayer420
Just got killed by a noob with lag boosting. My rage is at max.
Lag boosting? I'll show you lag boosting. I'm gonna kill you in 3 seconds.
