Origins and Historical Context of the Idiom “piss like a racehorse”

The idiom “piss like a racehorse” is a colorful expression that has been used for many years to describe someone who is urinating with great force or volume. While it may seem like a crude phrase, it has become an accepted part of the English language and is often used in casual conversation.

The origins of this idiom are not entirely clear, but it is believed to have originated in the world of horse racing. In the early days of horse racing, horses were often given diuretics to help them lose weight before races.
