A bum here is someone who asks for money on the street, usually for alcohol.  They are almost always unemployed and homeless.  Anyone here using the word "bum" the way a Brit would use it will probably attempt some sort of a fake British accent!  We're a strange lot.  Do you use American accents just for fun?

A tramp here is either an old-fashioned word for a bum (it was used during the Depression in the 30s when men used to jump on freight trains to get from place to place), but a tramp can also be a woman of loose morals.  Not necessarily a hooker, just a gal who sleeps around.  Of course men who engage in similar behavior are "studs," which should give you an idea of the equality of the sexes in this GREAT nation of ours!  LOL!

Hookers here are prostitutes.  There's no other meaning of the word that I'm aware of.

I loved SOAP!  Cracked me up.  I'm not much of a TV watcher and never have been, but I made a point to stay up and watch that show while it was on.
