I get this question often once I've peaked a girls interest. They've shown interest in wanting to know more.

I would answer indirectly and fuck with them but at this point I've already been doing that a lot and it could slip into over-gaming.

There could be a happy medium where you don't lose your frame but say something coy like "what is it that you'd like to know". Since this comes up a lot, trying to get the right mentality and type of response for this.
