LaShitivus
A professional who simultaneously meets the peter-principal standard & definition while being a functioning alcoholic. This person despite all their "unknown" short-comings (including but not limited to, inability to spell, read and write on a 10th grade English level) and lack of general intelligence will be successfully promoted up the ranks. A LaShitivus will survive and thrive in fortune 500 companies and law firms a like. The reason for the LaShitivus's success remains unknown, but his taste in scotch, women and suits is impeccable.
As an associate young LaShitivus is sent to court to file a minor motion. Bored and hung over LaShitivus forgets to file the motion and hits on an attractive court reporter - who turns out to be a young partner's wife. Upon his return Senior Partners hear about the spectacle and find this encounter amusing. They then offer LaShitivus a full time position after graduating.
