There's a girl I work with who always hits on my boyfriend.
She's got her own guy, apparently but that doesn't seem to matter to her when she sees my guy.
She hits on him every chance she gets and when he comes to pick me up from work, (she and I work together) she always tries to hug him and even if he doesn't hug her back, she still will hug him and it is usually a full on body hug, with her arms around his neck and one time she even kissed his cheek.
Way out of line, and she's lucky I wasn't around to see that.
Still, I heard from my boyfriend that the other day she walked up to him and asked him if he and I were truly together and when he said yes, she actually said: "She's kinda thick."
That really set me off, because you'd think my boyfriend would say something to defend me, but he didn't, because he didn't want to make more waves.
According to him, he was so shocked, he couldn't think of anything at all to say and walked away without saying anything in response!

Now, I'm a tall girl and am in the process of losing some weight I've gained recently, but I am far from "thick."
I know this girl was just saying that to make herself look better and she is far from perfect herself.
In fact, she is about as white trash as they come and she has a huge belly, so if anyone is thick, it would most def. be her.
Anyway, we work in a bar together, so now all etiquette has gone out the window as far as she's concerned - I'm putting all politeness aside and I would REALLY love to tell her where to go, but I want to really give it to her in a way she can understand. Normally, I ignore rude idiots, but this one deserves everything she gets and I don't want to waste a good opportunity.

Anyone have any suggestions for what I can say that would make her shut the hell up?
Yeah, I know this is really immature and I know it's sinking down to her level, but sometimes it's justified!
