Tequila Slammer

A Tequila Slammer (known in Mexico as a muppet or mópet) is a cocktail served in a rocks glass. It is made with equal parts tequila and a carbonated beverage, often 7 Up, ginger ale, lemonade, or Mountain Dew (although the original mix was with lime-lemon Yoli—a soft drink from Acapulco—and in the mid-'80s the grapefruit-flavored soft drink Squirt was popular). Champagne can also be used, and this is called a Slammer Royale or Golden Slammer.
