Is this flirtatious?

I was eating lunch at a table with several people today. There was a girl sitting next to me that I had never met before. We got along good over a few hour lunch. She had a nice outfit on and a great . We were sitting on very hard, wooden, and uncomfortable chairs. As we were getting up, she rubbed her and told me that her caboose was in serious pain after that much sitting, laughed, and left. I do not doubt that she was sore(my was hurting also but I didn't say anything) but was that a sign of flirtation? Why would she say somethng like that to someone that she does not know? I hope that she was. I really liked her flaunting her like that. Maybe, I am weird but I almost wish that I had gotten to kiss her to make it feel better!
