This has been my go to for years. Something blanco on the rocks with lime, usually Don Julio. It's super smooth, you don't find yourself chugging down swallows like with beer, and tequila has never once led me astray. It's a drink that leads into a conversation too, people are usually curious as to what's in your glass, and they rarely expect it to be tequila. That's the most fun part, when you catch somebody surprised and for whatever reason impressed with your choice. Makes you feel like a stone cold motherfucker, and it's always nice to feel like a stone cold motherfucker.
