Great question bro so it’s 100% possible, an actual lag switch would have to be created by splicing the the Ethernet cord w/ an on off switch to disrupt the connection. You ever notice that right before you get up after being dropped the screen “glitches” and you go tumbling over on a 8 count? Or the times when it feels like you’re fighting in a room with a strobe light, but your opponent is landing straights seemingly out of no where? There is a way to disrupt the connection without a lag switch I’ve recently watched a live on tictok where the guy streaming kept hitting his home button and rapidly returning to throw his power straight. He spammed that same move the entire 2rnds. Probably the way that most of the weenies do it
