While traditionally, the Blue Hawaiian is a rum drink, using tequila isn't that uncommon, either. This is my usual go-to for the tequila version.
Start by rimming your rocks glass with roasted coconut shavings Then in a tin, mix: 1.5oz Blanco tequila 0.75oz Blue Curacao 2oz Pineapple juice 1oz Creme of Coconut Add some ice, shake vigorously for 15-20 seconds, then open pour into the prepared glass.
I thiiink this is meant to evoke Ranma 1/2? Become a girl with cold water, become a guy with hot water, as represented by the eyelashes and chest disappearing? Not sure how to go about applying the relevant tags to such a case though, if others agree (such as, do we add genderswap (ftm)?)
Edit: commented that, edited it for context, and in doing so kind of answered my own question haha; think it would make sense to add such tags even if the implication is that her default state is male here
