Muttonbuster
A muttonbuster is a combination of rodeo whiskey (preferably Pendleton) mixed with your childhood favorite root beer (preferably Mug) on ice. Invented by a cowpoke from Oakdale, CA named Mike Brazil. So next time you're throwing back some fine rodeo whiskey and want to mix in some childhood root beer memories then saddle up partner, it's muttonbustin time!
