A homeless person. Not necessarily lazy but is usually considered to be because of their social rank. Also inlcuding people that beg for change and people sleeping on the streets.
That guy that is always sleeping under that tree with worn clothes and has no home to go to is a bumb.
Funny how some of you "bumbs" that cry constantly about refs and every other injustice that you see, come at the Difference when I voice my opinion, when all in your world is fine or you get a win or two.
Combination of the words bum and numb. Bum that has become numb from excessive sitting. Like sitting in front of a laptop in hong kong airport for six hours.
