Delulu or delulu is a shorter term for delusional mostly used in the Kpop world to describe and/or mock a fan that believes they'll date, marry, or befriend their favorite idol.
Person 1: Bang Chan is so hot. One day i will date him! And if i don’t get him i will get Lee Know!

Person 2: Bro you’re delulu…

———————————

Person 1: Maybe i will have my Y/N moment when i go to the BTS concert and Jungkook will notice me!

Person 2: You are absolutely delulu. Are you okay?

(Although don’t we all wish to have our Y/N moment?)
