A Fat L
A Fat L is when you mess up so bad it’s like you were hit by a truck and your brain fell out. It means you lost really badly, like you were sleeping when the game started.
"I took a Fat L because I fell asleep during the game. My opponent won by default."
"My team took a Fat L so bad I think we were all dreaming."
"I got a Fat L because I lost to my mom. She’s 50 and still beats me at games."
