When you walk into a roomful of interesting people, check out each person’s beverage. You can tell so much about a person by what he or she is drinking. Use this handy guide to help you along.

The Martini
This Drink exudes classic sophistication and is favored by veteran Party Girls everywhere. Martini Guys are harder to come by. Be thankful if you’re lucky enough to find one. If he’s choosing a martini, it shows that he has discerning taste in drinks—which probably carries over into other areas of his life. But watch out—he might have ordered a martini because he is trying too hard to impress the ladies!

Extra tip: You can assume that anyone holding a martini has good coordination. It takes a very steady hand to avoid spillage with one of these babies.

Wine
Wine is a tricky elixir. A true Party Girl drinks wine only when there’s a stellar wine list to choose from. You’ll know she knows her stuff if she sticks with a refreshing Sauvignon Blanc or a classic Cabernet.

If you spot a guy with a glass of wine, he could be Metro or Euro, making him a great candidate for interesting conversation. A nice glass of wine says “Details are important to me.”

Extra tip: Steer clear of the guy drinking white zinfandel. Unlike other wines, a glass of white zin usually says, “I live at home with my mother and don’t have a job.”

Beer
While a Party Girl has a beer now and then, beer has one real purpose: to tell all about the types of guys in the crowd. One real rule applies here: type of beer = type of guy. The guys don’t have to speak—their beer speaks for them. Check out this handy beer translator:
