Psychologist Glenn Wilson tells the BBC that the way each person holds a glass says volumes about his or her personality. Some examples: the “Flirt” (almost always a woman, according to Wilson) holds her glass with splayed fingers and often places it provocatively near her cleavage, sometimes teasing the rim with her finger. The “Gossip” (also generally female, Wilson says) may use her glass to gesticulate, or lean over it confidentially. The “Fun-lover” (which can be either gender) take short swigs from bottles so they don’t miss out on the conversation. The “Playboy” (generally male) uses his tall glass or bottle as a phallic prop. And the “Browbeater” (also usually male) prefers large glasses or bottles, which are wielded as symbolic weapons. “The next time you’re in a bar, it might be worth thinking about what you’re saying to the people around you, just by the way you’re holding your glass,” Wilson says.
