Rantipole (3 syl.).
A harum-scarum fellow, a madcap (Dutch, randten, to be in a state of idiotcy or insanity, and pole, a head or person). The late Emperor Napoleon III. was called Rantipole, for his escapades at Strasbourg and Boulogne. In 1852 I myself saw a man commanded by the police to leave Paris within twenty-four hours for calling his dog Rantipole.
