Lagging cheat?

Can anyone tell me where there is any information about a cheat where, during a fight, one team suddenly causes you to experience huge lag and automatically lose the fight? I don't have a problem with the Internet, and I've had several such cases recently. We have a fight and suddenly I get huge lag and I can't do anything and it kills me... lvl 18. What is this even supposed to be?

Does anyone have such situations? Has anyone seen any videos about this? I'm sure such a thing exists, because it happened to me many times, but when I was fighting for 1st place with the last team and suddenly something like that happened again, I decided to write about it now.
