How do you hold your drink?

Think about the last time you were out at a bar with friends. Now, think about what you were drinking and how you were holding your glass: Casually? Daintily? Firmly?

A new study by psychologist Glenn Wilson for Australian bar chain Walkabout Bars says the way you hold your drink reveals much about your personality. He studied the body language of 500 partyers and divided them into eight personality types.

According to Wilson, the eight types are:

1. The Flirt: Usually a woman, who holds her glass with dainty, splayed fingers and uses it in a provocative way. She may position it over her cleavage so as to draw attention to her attributes or peer over the rim to make eye contact when taking a sip. She may "tease" the rim of the glass with her finger, perhaps dipping it into the drink and sucking it dry.
2. The Gossip: This (mainly female) drinker tends to cluster in all-female groups talking about other people, and can be critical. She holds a wine glass by the bowl and uses it to gesticulate and make points in conversation. She is inclined to lean over her drink, in towards others so as to speak confidentially.
3. The Fun-lover: This type of drinker may be a man or a woman, who drinks to be sociable and values togetherness. A convivial individual, he/she enjoys being with their friends, and likes a laugh. Swigs taken from bottled drinks are short, so they don't miss out on chipping in with the conversation. The bottle is held loosely at its shoulder for ease.
4. The Wallflower: This is a shy individual who holds the glass protectively, not letting go, as though afraid somebody will take it away. Palms are kept hidden and the glass is used as a social crutch – the drink is never quite finished, with a mouthful left in case of emergency. It may be drunk through a straw, which is fidgeted with, and used to stir the drink between sips.
5. The Ice-queen: This is a mainly female type whose natural style is cold and defensive. She drinks from a wine glass, or a short glass, which is held firmly in a barrier position across the body so as to deter intimate approaches.
6. The Playboy: This man is the active, self-confident, Don Juan-type seducer. He uses his (usually long) glass or bottle as a phallic prop, playing with it suggestively.
7. The Jack the Lad: This "peacock" is conscious of his image and will drink a bottled beer, or cider. Inclined to be confident and arrogant, he can be territorial in his gestures, spreading himself over as much space as possible, for example, pushing the glass well away from himself and leaning back in his chair.
8. The Browbeater: This pugnacious type is again mostly male. He prefers large glasses, or bottles, which he uses as symbolic weapons, firmly grasped, and gesticulating in a threatening, "in the face" kind of way. Something of a know-it-all, he comes across as slightly hostile, even if only through verbal argument, or jokes targeted at others.

I fall into -- interestingly enough -- The Wallflower category. I grasp my drink with both hands and swirl my straw. But as the night goes on and more drinks are consumed, I quickly become the Fun-lover. Funny how that happens.

Where do you guys stand? Do you use body language to determine whether or not to approach someone?
