Interesting description. I guess what we have here is a different understanding or perception of what flirting is. In my mind and what I describe specifically is something someone does actively toward a person of interest. I am talking about making gestures toward someone, smiling, saying hi in a more inviting way, etc. Not something in my mind that can be misinterpreted by the wrong person typically.

The other thing, seems to me to be less flirting and more of flaunting ones self in front of a crowd or group. I can see that drawing in the wrong person but what I'm talking about is going out of your way to show that you've noticed a specific person and making it clear you're interested in finding out more, getting to know them, making conversation in the interests of possible date.
