Dear Sister, what is a "power flirt"?

Hmm, an interesting conundrum this one. The Holy Bible, Wikipedia, doesn't have a listing for that specifically, but does this mean the term does not exist??
Sister doesn't think she can do any more ogling the google, wander the wiki or delve into the ning. Mite be one of those riddles wrapped in mystery, just like a chiko roll, umm in other words maybe not...
