Prepare Glass: Fill a large pint glass, mason jar, or highball glass completely to the top with fresh crushed ice.
Add Spirits: Pour the 2 ounces of orange-flavored vodka and 1 ounce of triple sec directly over the crushed ice.
Juice & Shake: Add 3 ounces of fresh-squeezed orange juice. Transfer the entire mixture into a cocktail shaker, shake vigorously for exactly 10 seconds, and pour everything back into the chilled glass.
Top & Fizz: Top the drink with a healthy splash of lemon-lime soda to give it its iconic, refreshing fizz.
Garnish & Serve: Garnish the rim with a fresh citrus wheel or orange slice and serve immediately with a straw.
