Delulu
delulu; delightfully delusional, lost in wishful thinking (playful internet slang)
Origin
Anglicism, a playful, childishly sounding reduplication of 'delusional'. The term arose around 2013/14 in English-language K-pop forums (e.g. OneHallyu) for fans with unrealistic, parasocial hopes about their stars. Through viral TikTok trends - such as the phrase 'delulu is the solulu' - it became popular with Gen Z and Gen Alpha and usually denotes, jokingly, an unrealistically optimistic wishful thinking.
