Milk a Horse 

To firmly grasp and stroke the, baseball bat sized, hot, sweaty and slippery meat shaft attached to the underside of a stallion, which commonly known as a horses cock. This act is generally frowned upon in most societies. It it is simply unforgivable to any and all people who attempt it and succeed. It is even especially unforgivable (and uncontrollably hilarious) to proceed to drink any/all of the horse cum that may ejaculate violently into the milker's face.

"Everyone check it out! Nadsack is about to milk a horse!!!"
