Come back when your teeth are fixed!!

It is so wrong when disgusting people think they have a chance with me. I'm not talking about the gentle secret admirer type, or the wolf whistling stranger.
No, I mean the guy who is after random female action, decides that the closest person on their radar is moi, and decides that 'no' is some strange female way of saying 'come give it to me RIGHT NOW', decides to bust their moves with no encouragement whatsoever, then doesn't take no for an answer.
What are they THINKING!! Surely, if I was interested, I'd come over and talk. But. If I'm staring at my drink with fierce concentration, it probably means I'm avoiding eye contact.
Like the time I was at a birthday party and a guy I know seemed to be trying to pick up every girl there. When he got around to me, surprise surprise, I wasn't interested either. In the memorable words of G, "come back when your teeth are fixed". Did he get the picture? Nup.
Do I look like someone who would be interested in blokes who look like albino rottweilers with scrubbing brush hair?
