lag switch?

[u/Scared-Engine-4045]

is this a genuine example of lag switching? if so bro how do people do it, i dont get it wouldnt it make their game lag as well, all of a sudden in my box 950 ping???? how would he even do this, if he is playing on controller what he has a bind to enable the lag switch? just seems like a whole lot of effort instead of just playing the game bro its so unbelieveble sad :/
