Anyway, the eight types that have been "discovered", from TTel:
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. Assuming her agenda is appealing, the best way to approach is with reciprocal flirtatious gestures.
Celebrities: Jordan, Paris Hilton, Kate Walsh (from The Apprentice)
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. This person already has a close-knit social group with little inclination to extend it, therefore advances from outsiders are not usually welcome.
Celebrities: Kate Moss, Sadie Frost.
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. This type of person is always happy to extend their social circle. The best way to approach them therefore is to leap directly into light, good-humoured conversation and make them laugh.
Celebrities: Sarah Harding, Helen Chamberlain (from Soccer AM)
4. The Wallflower: This is a shy, submissive 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. The drink is small (maybe half a pint of lager for a man). It may be drunk through a straw, which is fidgeted with, and used to stir the drink between sips. The style and pace of drinking is an echo of those around them (very little is initiated). This individual needs to be approached in a gentle, sensitive way, with perhaps a few understated compliments to build self-confidence, but may eventually warm to overtures.
Celebrities: Scarlett Johansson, Natalie Portman
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. It is usually a waste of time approaching this woman; she may be ready with a castrating put-down.
Celebrities: Victoria Beckham, Debra Barr (from The Apprentice)
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. He is inclined to be possessive, and can be tactile with his female companions.
Celebrities: Russell Brand, David Walliams
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. If he's drinking with his mates, he would be unlikely to welcome approaches from outside the group, unless sycophantic and ego-enhancing.
Celebrities: Peter Andre, David Cameron, Jason Statham. The "ladette" (e.g. Lily Allen) is a female approximation to this male archetype.
8. The Browbeater: This rather 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. He should be approached with great care, or not at all.
Celebrities: John Prescott, Russell Crowe (with Naomi Campbell as a female equivalent), Gordon Brown.
*This goes back to when I used to smoke and as a right hander, I had more control over the fag in my stronger hand then my weaker left, which simply clung onto a pint glass. It's a habit I am stuck with today, but at least it's a reasonable explanation instead of this star gazing cobblers.
