peeing like a racehorse

Voiding with volume

Peeing like a racehorse means urinating copiously and forcefully, typically after holding it for a long time: I've been driving for three hours—I need to find a bathroom. I'm going to pee like a racehorse.

The comparison evokes the impressive volume and pressure of a horse's stream.

The expression is informal and mildly crude.
