I think being thrown in a brand new situation does that for me. If that happens. Playing around with my understanding is more for my own sake though or for working around something.. a learning experience.. rather than anything to do with creating an affect on people (not to say I wouldn't screw with people, but that's not the point). Also, once I am redefining things, I've probably been weirder or ballsier in some way than ESTPs. Maybe it's Ni.
With me the bigger my global understanding the more I play.
