A lagsak is someone who can't play a game worth their salt, but they'll scream at the top of their lungs for the best player in the league.

This lagsak was yelling 'GO BRUINS!' at 2 a. m. even though they lost the game 4-1.

My cousin is a lagsak. He watched the whole Super Bowl and still didn't know how to catch a ball.

That lagsak tried to play Fortnite and couldn't even build a wall straight.
