Old Slang for Bozo or Bum depending on context.
Written as " 'bo ", this slang had common usage prior to the 1960s. However, in recent years the term has
experienced less usage, excluding some small groups or the elderly, and should be avoided in every day use as it will most likely be perceived as slang for Body Oder
Written usage dates back to at least the 1910s, as evidenced by its use in the Union Song "The Tramp" by Joe Hill, and can be assumed as having been around prior to that point.
Documents, letters, songs, movies, and other things dating prior to the 1960s using 'bo should be assumed as referring to a bozo or bum and NOT Body Oder unless evidenced
otherwise.
