Signs you're delulu: (1) reading into three-word replies, (2) building a shared future around one coffee, (3) narrating his texts in your head. Diagnosing yourself is the first step; choosing not to recover is the brand.

"He sent me ‘lol' back. I'm already picking out rings. Peak delulu."

Why is this section here?

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
