usage, a tramp is a long term homeless person who travels from place to place as an itinerant vagrant, traditionally walking or hiking all year round. In British English meanwhile a tramp simply refers to a homeless person, usually not a travelling one. While some tramps may do odd jobs from time to time, unlike other temporarily homeless people they do not seek out regular work and support themselves by other means such as begging or scavenging.
