Few people officially approve of flaunting their proteans. If one's gender forces one to have this specific kind, one has got to have a place to stash them and then let them come out "unexpectedly". The other way is to do it knowingly, but that is normally coupled to the affirmative kind. Flaunting uncertainty is therefore necessarily trans-gender, which can indicate an extra strong display, in case of attractiveness, or a warning to back off, in case of craziness.
