What Does “Delulu” Mean?

The term delulu is a playful, shortened version of “delusional.” But unlike the serious meaning of delusional in psychology, delulu is mostly lighthearted and humorous.
People often use it to describe someone who:
- Has unrealistic expectations
- Lives in a fantasy world
- Refuses to accept reality in a fun or exaggerated way
For example:
“She thinks her favorite K-pop idol will notice her in real life — she’s so delulu!”
Here, delulu isn’t meant to offend deeply; it’s a teasing, relatable way to call someone out for daydreaming or overthinking.
It’s worth noting that tone matters. In some contexts, calling someone delulu can be a joke, while in others, it might lightly criticize someone’s judgment.
