Get the rocky mountain goat piss mug.
A colloquial term used in reference to the popular sports / soft drink "Mountain Dew".
While hung over in the rocky mountains after a blinder night you may find a need to "get on the goat piss" in retrospect of the previous nights heavy drinking session.

In drinking such green coloured salty flavoured beverages some may comment : "Hard night eh?..On the goat piss I see" in reference to the consumption of the Rocky Mountain Goat Piss.

One would acknowledge this comment with a nod and knowing smile.
