Or is she? Apparently Oreos are available in England, but they don't seem to be too common. Would they be an obvious pig-out food to a British person? If not, are there any other name-brand cookies/biscuits that come to mind?
While I'm at it, what sort of florid language does she use to complain about the boyfriend she's just dumped? He's tall and dark and handsome and very full of himself. So far she thinks he's a "bloody wanker" and a "git," but I would love to hear your creative suggestions.
ETA: Thank you for all the suggestions! It was very fun to read. :D I think I've got enough to go on now.
