Place your rocks glass on the table.
Pour 1 part of tequila into the glass.
Now, top tequila with 1 part any of your favorite carbonated drink like 7 Up, ginger ale, lemonade, Lemon-lime soda, or Mountain Dew etc.
Cover up your shot glass with a clean napkin or the top of your hand, banging it on the table so that it fizzes well.
Pick the glass up with care and drink the whole Tequila Slammer Cocktail in one gulp. Get pleasure from the after-effects.
