delulu
What does delulu mean?
Delusional — usually in a light, self-aware way, about something you badly want to be true. Often paired with the phrase "delulu is the solulu" (delusion is the solution).
"I'm being delulu but I really think we're going to win the league this year."
Origin
Reduplicated baby-talk shortening of "delusional", originating in K-pop fan communities before going mainstream on TikTok.
