Internet Slang

Delulu means delusional in a playful, internet-slang way, usually for someone acting like a fantasy is real.

What People Mean When They Say Delulu

Delulu is the casual, shortened version of delusional. Online, it usually points to someone believing something wildly unrealistic, especially about love, fandom, or a situation they are clearly reading too optimistically.

The term often carries a wink with it. People use it to roast a fantasy, laugh at their own hopeful thinking, or call out someone who is acting like the outcome is guaranteed when it is not.

How Delulu Shows Up Online

You will see delulu in group chats, comment sections, fan posts, and self-roasts. It shows up a lot around celebrity crushes, shipping, dating hopefulness, and any situation where someone is building a story that reality does not support.

It can be used lightly among friends, but it can also land as a small insult if it is aimed at someone else's judgment. When people say it about themselves, it usually sounds more charming and self-aware than rude.
