lag boosting
When you're in a game and you get killed because someone else had lag boosting and you're just like no way and you want to kill them back.
"No way! He had lag boosting. I'm gonna kill him back.", @HaloNoob
I got killed by lag boosting. I'm not even mad, I'm just gonna kill him back.
Lag boosting? I'll show you lag boosting. I'm gonna kill you.
