laggamuffin
A laggamuffin is someone who blames their lag on everyone else and still manages to be the worst player in the room. They’re like a broken toaster, but with more rage.
"You’re the one with the lag!", a laggamuffin yelling at their teammate.
"I can’t even move because of you!", a laggamuffin who can’t even walk in a game.
"I’m not lagging, I’m being sabotaged by the Wi-Fi!", a laggamuffin who thinks the Wi-Fi is out to get them.
