- It is mostly playful — fans joke about their own delulu.
- Key point: delulu people usually know they’re dreaming. That’s the fun.
Think of delulu as: fantasy mode, on purpose.

People call themselves delulu more than they call others — it’s self-deprecating humor.

- “My delulu era is buying concert tickets for a city I’ve never visited.”
- “Stay delulu, bestie, it might come true!”

It is usually written in lowercase (delulu).

Delulu vs Delusional

Common Mistakes to Avoid
Mistake 1: Using delulu seriously.
