lag munch
A lag munch is a person who takes forever to load stuff and makes everyone else mad because their game turns into a mess.
This lag munch took 20 minutes to log in. I was like, 'are you even trying?'
My brother is a lag munch. He took so long to load his character, I gave up.
This lag munch kept lagging me out of the game. I was so mad, I yelled at my screen.
