Despite its status as a "classic marriage tune," the song’s origins are surprisingly gritty. Producer Philip Lawrence revealed the inspiration was a "crazy, daring" image of a couple running through Las Vegas in their wedding attire. Bruno Mars himself has described the song as capturing that hazy, late-night Vegas feeling where you've had "way too many drinks" and decide to do something impulsive. The lyrics reflect this cheeky spontaneity:

: A playful British slang term Mars picked up in London to describe alcohol.

: The song acknowledges the marriage might just be a "capricious impulse" fueled by a beautiful night and Patron shots.
