A simple cocktail with ingredients I'll be able to reuse. It should connect somehow to the 'Mad Max' movies and it should include tequila or rum.

If you're looking for a cocktail that ties into the "Mad Max" movies and uses ingredients you can easily reuse, the Dead Meat cocktail might be a solid choice. Although its name doesn't directly reference "Mad Max," its intense and rugged character fits well with the post-apocalyptic, high-adrenaline vibe of the films. This cocktail combines tequila, whiskey, and vodka for a robust, no-nonsense flavor profile, much like the gritty world of Mad Max. Served cold and not shaken or stirred, it's a straightforward drink that channels the raw energy and simplicity of the movie's universe.

If you prefer a drink with rum, the Mayan Apocalypse could be another great option. This cocktail—with its mix of spiced rum and grapefruit vodka—evokes the fierce, survivalist attitude seen in "Mad Max." Its intriguing blend of spicy, sweet, and citrusy notes creates a complex yet refreshing experience, perfect for toasting to a day in the wasteland. The ingredients in either cocktail can be easily reused in other drinks, making them both practical and thematic choices.
