Delulu is short for "delusional," and it is often used by 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.
