Take a sharp knife and carefully cut a fresh lemon into two equal slices. Pick one of the slices and rub it all around the rim of your cocktail glass. Now, dip the wet rim of your glass into salt. Place the rimmed cocktail glass in refrigerator to chill.
For the time being, fill 1/4th of your cocktail shaker with Ice cubes or crushed ice.
Pour 1/2 oz of Vodka, 1/2 oz of Watermelon Pucker, 1/2 oz of sweet and sour mix, and 1/2 oz of orange juice into the cocktail shaker.
Note: The Pucker Up Cocktail is best prepared with freshly squeezed orange juice. For this purpose, take two fresh oranges and peel them properly. Now, break them into sliced and remove their seeds. Place the orange slices in an electric juicer and extract their juice. Or else, you can use the packet orange juice as well.
Seal your cocktail shaker in order to avoid over-splitting of the cocktail.
Hold the cocktail shaker tightly and shake it vigorously for few seconds until the ingredients mix and the ice cubes dissolve.
Remove the lid of the cocktail shaker and strain the Pucker Up Cocktail into a rimmed cocktail glass.
Serve it straight up or drink it yourself.
