en plein délire

Tap to hear it pronounced

What it means

A playful shortening of "delusional," used to describe someone confidently believing something unrealistic (often about a crush or a celebrity). Jumped from K-pop fan communities to mainstream English in late 2022; Collins Dictionary added it in 2025.

Is this actually used?

No French speaker says "delulu" itself — the closest natural equivalents are "être en plein délire" (to be totally deluded) or the older idiom "se faire des films" (to make up stories in your head). Neither is a 1:1 translation; both need the surrounding context to land.

Example

Elle est en plein délire, elle pense qu'il va l'appeler.

She's delulu, she thinks he's going to call her.
