The expression "tip top" likely originates from the 16th-century term "tip-top," which referred to the highest point of something. It combines "tip," meaning the top or extreme end, with "top," reinforcing the idea of excellence or peak quality. The phrase gained popularity in the 19th century, often used to describe something that is in excellent condition or of the highest standard. Its playful redundancy emphasizes superiority in a lighthearted manner.
