piss like a racehorse

Void bladder dramatically

To piss like a racehorse is to urinate copiously and forcefully.

The expression is vulgar but common, typically used by someone announcing urgent need or describing relief after a long wait: I've got to piss like a racehorse.

The image comes from the impressive volume horses produce.
