A stupid fucking word that cringe people think is ‘funny.’ A short version of delusional. No, you’re not ‘delulu’ because you like a guy and say he likes you back, since you know he doesn’t. Delusional people usually don’t know they’re delusional. So, disrespectfully shut up.
Person 1: “Omgg, I’m so delulu he wants me back.”
Person 2: “Shut up you fucker, you’re not delusional.”

Delulu is slang for delusional, commonly used amongst KPOP fans. Not used for the mental disorder but more calling out crazy fans. If a fan starts thinking sexually about an idol, starts writing fanfics about them is when someone would get called delusional.

An example is when fans start thinking they have a chance with a certain idol, or replace a groups official title with another is when you would call someone "delulu".

Another meaning is for people who see delusions commonly from a disorder or mental illness
Once: "Nayeon is Korea's it girl, if you say otherwise you are delulu."

blink: " BTS isn't the biggest group"

"Delulu" means delusional, its a word stupid teenage girls use because they have a crush. They're romanticizing being delusional even though its very serious.
"He liked my story again, he must like me!"
"Omg your delulu is becoming trululu!"

"She isn't 'delulu', she just has a crush.." is what a normal human being would say.
