Noun or verb. To facehausen is to invent insane or even impossible events at remote locations for yourself on a Facebook account in your own name on which you have also invented a fantasy profile. The aim of a facehausen may be to blow smoke over your actual activities and profile, to reward idle curiosity with absurdity, or simply to have fun and generally ass around. By extension, a facehausen is any elaborate ploy in which a patently impossible claim is made or stance is taken in sarcasm, in order to deflect a line of ad hoc interrogation--in place of rendering the woefully dull "It's none of your freaking business." Formed from "Facebook" and "Münchausen," the latter in reference to The Fantastic Adventures of Baron Münchausen, in which the Baron claims to have had many bizarre and even impossible escapades. Related to "tweethausen," a similar ploy, but more succinctly purpetrated on Twitter.
I set up a Facebook account with my name and the profile of Indiana Jones. Nobody noticed the facehausen, so I actually started wearing a fedora and leaving my office by the window instead of the door. I drew the line, however, at ransacking flea markets for crystal skulls.
