Delulu, Explained: K-Pop's Favorite Delusion Is Now a Group Activity

On Nov. 6, the @euronews.romania TikTok account posted that K-pop fans in Romania had taken part in a collective "delulu" exercise, imagining a shawarma outing with their idols, with some of them going "delulu pro max" and inviting the whole group. Delulu is fan slang for knowingly delusional hopes, the wishes you announce with a straight face and zero expectation of a callback, and this week it worked less like a private joke and more like a group activity: that post has 124,608 plays.

What it means

Delulu is a shortening of "delusional." The Guardian drew the line that makes the word useful: self-belief is confidence in your own abilities, while delulu is confidence beyond all ability.

The register moves depending on who is holding it. Aimed at a stranger, it can still land as the old insult. Aimed at yourself, it is a wink. Among fans it is usually affectionate, a way of naming the gap between what you want and what is actually scheduled, and of enjoying the gap anyway.

It also travels in compounds. "Delulu is the solulu," which El País translated as delusion is the solution, is the slogan version. "Delulu pro max," from the Romanian post, is the escalation setting.

Where it came from

According to The Guardian, delulu began about a decade ago as an insult that K-pop followers aimed at fans they saw as obsessive, the ones convinced they would befriend, date or even marry their favorite stars. El País described it as an ironic, hypertrophied and somewhat paranoid version of positive thinking that took Generation Z slang by storm, with the English-language mainstream press left theorizing about what it might do for the workplace and for romance. The same piece, published Nov. 30, 2023, noted the delulu hashtag had nearly six billion views on TikTok alone.

Then the dictionary came for it. Cambridge University Press & Assessment announced on Aug. 18, 2025 that delulu was among thousands of new English words, phrases and meanings added to the Cambridge Dictionary, in company with skibidi, tradwife and broligarchy. The Hindu reported on Nov. 18, 2025, citing PTI, that six thousand new words had entered the dictionary that year.

How fans are using it right now

@rizzhypen posted an ENHYPEN Jay edit on Nov. 7 captioned "I'm in delulu land. Good job with this fan service Jjong." It has 38,156 plays and 11,336 likes.

@princess_gehl posted on Nov. 5 about the Jeolee fan condition: "One minute kilig, next minute confused, tapos delulu ulit." That one has 46,887 plays and 6,478 likes.

And the Romanian post from the top of this entry is the week's clearest case of fans running the bit together instead of alone, complete with an invitation for the entire group.

In the headlines

The Korea Herald reported on Jan. 27 that KiiiKiii unveiled the group's second EP, Delulu Pack, at a media showcase at Yes 24 Live Hall in eastern Seoul, billing it as "a collection of (the members') new year wishes." The five-member act's six-track release is led by "404 (New Era)," a UK house- and garage-based track, and follows the 2025 EP Uncut Gem. Naming a whole release after a fandom word is a small sign of how settled delulu has become.

The Hindu reported on Nov. 18, 2025 that Cambridge Dictionary named "parasocial" its Word of the Year for 2025, announced that Tuesday and defined as involving or relating to a connection that someone feels with a famous person they do not know. The same report listed delulu among the year's new entrants.

Cambridge's own announcement on Aug. 18, 2025 put the word in the dictionary's pages, the institutional seal on a term that started life in fandom arguments.

Why it's having a moment

What shifted this week is the shape of the joke, not the vocabulary. Delulu used to be something one fan confessed; now it is something a fandom performs in public, which is exactly what the Romanian post does at 124,608 plays, with "delulu pro max" reserved for the fan who invites the whole group to dinner.

The week's posts also show the range: one edit tied to a single ENHYPEN member, one fan describing the whiplash of following Jeolee, one national fan community building a whole scenario. Different languages, same structure, wish first, punchline second.

And the word now lives in rooms that have nothing to do with fandom. It has been a dictionary entry since 2025 and a K-pop EP title since January, which means it can appear in a headline, a caption or a group chat without anyone needing the backstory.

How to use it (and how not to)

A few lines a fan would actually say:

• "Delulu is the solulu, so I'm manifesting a barricade spot."
• "I put the tour dates in my calendar before they were announced. Delulu pro max."
• "One minute I'm fine, next minute I'm in delulu land."

Etiquette is mostly about aim. Pointed at yourself or shared with other fans, it is warm and it is funny. Pointed at someone else's sincere hope, it can land as the insult it started out as a decade ago. And it is not a license to speculate about an artist's real private life, health or relationships, which is where the word stops being a joke altogether.
