Origin of Delulu
It is unclear who coined delulu, but its roots trace back to the K-pop community of superfans when they shortened "delusional" to "delu," then added an extra "lu" for the adorbs factor. It became popular in 2021, mainly among K-pop fanboys and fangirls to mock other superfans' beliefs.
For example, a K-pop stan who believes they will one day meet and start a relationship with their favorite idol may be called delulu by other stans. Shippers who ship different couples may also call each other delulu as they argue the merits of their OTPs.
Delulu then exploded in popularity in 2023 as it spread into the greater public's lexicon. Now, you may see or hear it in various contexts, including social media, messages, and in real life when someone is acting cray.
