worthless diluted liquid, such as beer or gasoline.
1. I was 17 when I was visiting my cousin in Memphis. He gave me a can of Coors beer. I tasted it for the first time. It tasted like industrial slop water. That or maybe panther piss. The worst beer in the universe.

2. I was driving on the New York State side of the Niagara Falls area and my car's tank was down about half. I wanted to get gaased up on the American side because Canada has a lot of gas brands of their own and I didn't know how suitable they are to my car's engine. I saw virtually no major brand gas stations on the highway, so when I saw a sign leading to a gas station at the Ticonderoga Indian reservation I took the exit. I fueled up, the gasoline brand was exclusive to the Iroqouis Confederacy. I was afraid that I was tanking up with panther piss but the gas was really good. My car operated nicely. No bucking and snorting. No problemo. Later that afternoon I crossed the border into Canada, where the hotel I reserved a room at was located.
