wig
The appearance or persona which one chooses to create for public view, as opposed to the 'real' self; the constructed public self. Hence 'wig out', to lose control of oneself, sometimes shortened to 'wig'; 'burned his wig', to depart terminally from normal behavior, or cause someone else to do so; 'blow someone's wig', to stun or astound someone.
Joe blew his boss's wig this morning by appearing in the office on time. The man is still gibbering.
