This is SO NOT ME. I don't drink, and even if I did, I wouldn't want a watermelon margarita and I hate red wine. But

to the remembering what you did when you were drunk. I could do that.
SCORPIO
Drinking style
Don't ever tell Scorpios they've had enough, for they'll smirk at you and quietly but intentionally keep tippling till they're hog-whimpering drunk, out of 100-proof spite. Scorpios like to drink, and screw you if you have a problem with that. Most of them see the sauce as something to savour in itself, and not as a personality-altering tool -- though if depressed, self-loathing Scorps seek total obliteration. But generally, they're fascinating drinking pals, brilliant conversationalists and dizzying flirts. They also remember everything -- especially what you did when you were blitzed. Only drink with a Scorpio who likes you.
Trademark cocktails
Just as a Scorpio can look you in the eye and smile while secretly plotting your demise, so does the brandy-laced stinger's sweet taste hide a potent amount of alcohol. If you want to get literal, serve them a scorpion -- they may not love tropical drinks, but it shows you're paying attention. Scorpio rules watermelon, so break out the blender and fix a pitcher of watermelon margaritas to seduce 'em -- though red wine will do the trick just as well.
