How you hold your drink may categorise you as 'flirty' or 'playboy'
All revellers fall into one of eight different personality types, which are given away by their drinking techniques, concluded Dr Glenn Wilson, a consultant psychologist at King's College, London, after observing over 500 drinkers in bars.
He analysed drinkers' body language and then advised on their openness to being approached.
He has categorised them as the 'Flirt', 'Gossip', 'Fun-Lover', 'Wallflower', 'Ice Queen', 'Playboy', 'Jack the Lad' and 'Browbeater'.
He said the most open to being chatted up were "the flirt, the playboy, and the funlover".
Harder to crack are the jack the lad, the ice queen, the wallflower and the gossip. The browbeater should be avoided.
"The simple act of holding a drink displays a lot more about us than we realise -- or might want to divulge," the Telegraph quoted Dr Wilson as saying.
The study was carried out for the Walkabout bar chain.
