I think donG. has a good point. (Sorry, didn't notice the page jump.) I mean, sure you over reacted, but it was a **** test if you think about it. The girl probably was baiting for some reaction and at least you responded proper. I used to have a GF who was like a 9.5 and she used to pull this crap on me all the time, but in VERY subtle ways. (like asking if the 'little boy' liked his...[whatever.]) Lucky for me, I usually missed it and looked like I didn't care what she thought. When I did catch though I always turned it into a joke at her expense rather then mine.
But now, your goal should be either to accept it, or try to avoid it. If she brings it up tell her you had an awful day, and it was all her fault. Which can be used for real good teasing material, tell her some outlandish story about how your dog died, you lost all you money gambling, and that you couldn't stop the doom ray today, and your super powers are starting to fade with age... Then it seems funnier then whats gone on. Or you simply diffuse with an apology and "lets move on" as everyone else said.
