What does ‘Full Monty’ mean?

After “The Full Monty” film was released in 1997, there was some international confusion over the phrase in which it was taken as a euphemism for stripping. However, “the full Monty” actually refers to pursuing something to the absolute limits.

“The full Monty” historically refers to an old tailor called Sir Montague Burton. Going “the fully Monty” meant purchasing a full three-piece suit, a shirt, and all of the trimmings.

“Our Christmas dinner had everything from sprouts to Yorkshire puddings. If you’re going to have a roast, have the full Monty!”
