What is round tuit?

A "round tuit" is a play on words, which playfully suggests that someone finally has a "round tuit" or a round-shaped object or token that represents a procrastinator's excuse for not having accomplished something. The phrase is often used humorously to indicate someone finally getting around to doing something they have been putting off or avoiding. It can also be used sarcastically when someone is still procrastinating despite having the "round tuit". Round tuits are often given as gag gifts or souvenirs. The origins of the phrase are unclear, but it has been in circulation for many years and is a popular expression among English speakers.
