Peak delulu is the single most unhinged, reality-adjacent belief you or someone else has committed to — the apex of magical thinking that becomes the stuff of legend among your friend group. It's not just casually misreading a text; it's the full manifested conviction that a celebrity you've never met is your soulmate, or that your ex 'definitely wants to get back together' based on liking a three-year-old Instagram post. Peak delulu moments are documented, shared, and eventually either vindicated ('I was RIGHT') or become cautionary tales told for years afterward.

Peak delulu was when I convinced myself his 3am Instagram story view was definitely a message — reader, it was not.
