Combine 1/4 cup fresh orange juice, 2 Tbsp. lemon-lime-flavored vodka, and 1 Tbsp. orange liqueur in a cocktail shaker; fill with ice. Cover with lid, and shake vigorously until thoroughly chilled (about 30 seconds). Strain into a 10-oz. glass filled with crushed ice. Top with a splash of lemon-lime soft drink.
