Delulu is the affectionate shortening of delusional, used self-deprecatingly about romantic or career fantasies you know aren't realistic but enjoy anyway. Delusional is the clinical word — a real mental-health term and, in normal speech, a much harsher accusation.

Delusional, affectionately — believing in something unlikely (usually a crush or dream outcome) despite the evidence. Often worn as a badge: "delulu is the solulu."
“"I know he has a girlfriend, but I think he's texting me cryptically. I'm delulu and I'm fine with it."”
Joking about your celebrity crush, manifesting outcomes you can't control, your 'delusional girlfriend playlist' on Spotify.
When you genuinely think someone's grip on reality is wrong, or in any medical/professional context.
Calling someone delusional in casual chat where you meant delulu — the word still lands as a real insult.
