pee like a racehorse

Void bladder dramatically

To pee like a racehorse is to urinate copiously and for a long time.

The expression draws on the impressive volume produced by horses: I've been holding it for hours—I'm going to pee like a racehorse.

Sometimes used as a boast about bladder capacity or as a warning that one needs to find a bathroom urgently.
