Lagertism
Lagertism is a disease that hits you when you’re stuck with a stupid friend, and you can’t even think straight because of it. It’s like having a brain made of soft cheese.
You: I can’t think straight. My friend: I’m not stupid. You: You are. You have Lagertism.
Your friend: I’m not stupid. You: You’re so stupid I think you have Lagertism.
You: My brain is like soft cheese because of Lagertism.
