Where Does delulu Come From?

The word delulu started in K-pop fandom spaces around the early 2010s. Fans used it to describe other fans who believed they had a real romantic connection with a celebrity or that their favorite group would behave in a certain way. Over time, it spread to mainstream social media and now applies to any unrealistic belief, not just fandom. The term is often used with a sense of community and inside joke, not harsh judgment.
