Coconut Watermelon Vodka Cooler

"Guilt-free Watermelon Coolers! So guys, I need help finding a word to describe healthy recipes that don't use any artificial or diet-y stuff (like trendy sugar-free sweeteners, which please-don't-judge-me but I really can't stand). The internet seems to call that category of recipes 'Skinny' but c'mon, seriously? Aren't we kind of beyond judging health foods by their ability to make us skinny? Anywho, this cocktail only uses fresh fruit juice, coconut water, and vodka (no syrups or artificial sweeteners) and it's probably the most refreshing thing I've mixed all summer."
