Yes. My particular favourite was a guy saying behind my back "I'd rather live with aids that with her" - something completely unprevoked, he was someone I thought was okay (not dateable). One day he was talking to me, one day he was talking behind my back. Thanks for that.
A lot of guys seem to think I'm a stuck up bitch, because of my accent (basically RP english).
Hooray for getting to know someone. :|
