delulu

What it means

Delulu is playful slang for delusional — believing something unrealistic about a crush, a celebrity, or your own chances, usually in a self-aware, funny way. It's rarely an insult; people happily call themselves delulu. You'll often hear the rhyme "being delulu is the solulu" (the solution) — meaning a little irrational hope never hurt anyone.

Examples

• She thinks her favorite idol will marry her someday. Bestie, that's delulu.
• I applied for the job with zero experience. A little delulu, but I'm manifesting it.
• Being delulu is the solulu — sometimes you just have to believe.
• He's convinced his ex is coming back. Fully delulu.

Where it comes from

Born in K-pop stan communities around 2014 to describe overly obsessive fans, "delulu" went mainstream on TikTok in 2023–2024, often paired with the rhyme "delulu is the solulu."
