Abrahamman
Abraham-man, the name given to that class of sturdy beggar in Shakespeare's days up to the Civil Wars who roamed through England begging and stealing. An Abraham man is described in a work (published 1575) as "one that walketh bare-armed and bare-legged and fayneth himself mad ... and nameth himself 'poor Tom.'"
