laggered
A lagger is someone who plays games with a broken computer and expects the rest of the world to suffer for it.
@laggerdude: I’m a lagger. My game lags so bad it looks like a zombie apocalypse.
DM: You’re a lagger. Your game lags so much I can’t even see you.
Tweet: My cousin is a lagger. He plays with a broken laptop and ruins the game for everyone.
