So I'm watching this terrible movie last night with Gwyneth Paltrow doing a horrid job at playing a hip Londonite with a career in PR which she has just lost and a cheating boyfriend. The other woman in the story has chance to meet her and during her next trist with the boyfriend refers to Gwyneth's character as: "Very pretty in a British, horsie kind of way." This is not the first time I have heard this sentiment made to refer to upright, pretty, British women as horsie. What gives? What does this mean?
