the.com/grandiosity

Confidence that skipped leg day on self-awareness and bench-pressed the ego instead.

means An inflated sense of one's own importance, talent, or grandeur that outstrips reality.

from Traces back to Latin 'grandis,' meaning 'great' or 'large,' which gave rise to 'grand' in English and the medical/psychological term 'grandiosity' describing exaggerated self-importance. The word picked up its clinical edge later, borrowed by psychiatry to name the inflated self-regard seen in certain personality patterns — so even its history is a little oversized, growing from a simple word for 'big' into a term for believing you're bigger than you are.
