What is a tramp and why do they smell?

Answer 1

• A tramp (use to be called 'hobos') are generally men that ride the rails (trains) or travel by foot hitch hiking. This was a familiar sight during the Depression or what was called 'The Dirty 30's.' They generally have difficulties finding a job or may not want a job due to Alcoholism, drugs or they may enjoy being a free spirit. Because of the way they travel and having to scrounge through restaurant garbage to finding a place to sleep they generally have little chance to bathe or wash their clothes. Another meaning to 'tramp' is a woman that gives out sexual favors without pay or for pay and some are not hygienically favored.
  

Answer 2

A tramp is a person experiencing homelessness or who wanders from place to place. The stereotype of tramps smelling may be due to lack of access to regular hygiene facilities or clean clothing, as well as potential mental health or substance abuse issues that can affect personal care.
