What is “delulu”? In everyday slang, “delulu” is shorthand for “delusional,” is defined as someone who is out of touch with reality—often in a playful, teasing, or hyperbolic way. Although it originates from the word “delusional,” in casual digital conversations it doesn’t always refer to genuine mental health issues.

Because slang evolves constantly, understanding terms like “delulu” can help parents, educators, and anyone interacting with younger generations stay up to date on what’s being shared online. While it is typically lighthearted, “delulu” can also venture into more problematic territory if used to mock or minimize real mental health challenges. In this post, we’ll break down its meaning, usage, and potential concerns.
What Does “Delulu” Mean in Slang?
As defined by Urban Dictionary, “delulu” is used to label an individual or situation that appears detached from reality. It can be directed at oneself (“I’m so delulu for thinking he’ll text back in five minutes!”) or at others (“She’s totally delulu if she thinks her TikTok will go viral overnight!”).
Over time, “delulu” has become a staple in teenage lingo—especially on platforms like TikTok, Twitter/X, and Instagram—where it commonly appears in memes and casual banter. While often harmless, it can sometimes trivialize mental health conditions or be weaponized in cyberbullying contexts.
How It’s Used in Real Digital Interactions
The term “delulu” pops up regularly in group chats and comment sections, usually with a humorous twist. However, it can also serve as a passive-aggressive remark questioning someone’s grip on reality. Here are some everyday examples:
Text Message
– Friend 1: “I’m gonna marry my favorite pop star one day!”
– Friend 2: “LOL, you’re so delulu!”
TikTok Comment Section
– Video: A TikToker talking about finally quitting their day job to become famous overnight.
– Comment: “We love the confidence, but that’s a bit delulu, don’t you think?”
Twitter/X Post
– Tweet: “I’m convinced I’ll be discovered in a coffee shop if I just keep singing out loud!”
– Reply: “Stay delulu, queen! Sometimes the universe rewards it.”
These examples show that “delulu” can be used lightheartedly (“Stay delulu!”) or as a mild insult questioning someone’s judgment.
