Delulu · Slang term · Full form: delusional · Origin: K-pop fandom, early 2010s
What does delulu mean in texting?
- “Delusional about someone”, the classic use. The original meaning: someone is being delulu about a crush, a celebrity, or a “ship” they are convinced is real. It is usually self-deprecating, “I’m so delulu for thinking he likes me back.”
- “Delulu is the solulu”, confident manifestation. Since 2023, TikTok has used delulu positively: unapologetic, joyful belief that your big goals will work out. Here delulu means choosing optimism over realism, almost like a joke version of manifesting.
- A joke label for an unrealistic take. Friends call each other’s plans delulu when they are wild but harmless, like expecting a million followers from one post. Tone matters: it is a tease between friends, not an insult.

When not to use delulu
Do not call someone delulu about a genuine mental health struggle, delulu is slang, not a clinical word, and it lands badly there. Skip it in professional settings too: no manager wants to hear “delulu is the solulu” as a business strategy. And if a friend is genuinely upset about a breakup or rejection, teasing them as delulu can feel dismissive, read the room first. For more on reading digital tone, check our think emoji guide.
