Who does this? Kate Moss, Sadie Frost

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.
