When two homeless bums make the beast with two backs.

One homeless guy will slide his hard throbbing cock into another guys tight arsehole, then thrust in and out, getting harder and faster until he blows his load. One up the bum, no harm done.

In the afterglow of this kinky bum sex, one hobo will then ask "spare some change" and the other will invariably reply "get a job, you bum".

Not to be confused with kinky butt sex, which involves perverted sexual acts performed on chain smokers while they're puffing away, using the dying butt of one cigarette to light the next.
Unable to deal with the City's ongoing housing problems, our fearless municipal leaders have brought in marketers to promote homelessness as a valid lifestyle choice. They're not "homeless people", they're "people experiencing homelessness" and their lifestyle promoted as one of kinky bum sex as people experiencing homelessness will do anything to keep warm.

An altogether more accurate term for 'bum sex', as there are actually willies involved in it, as these authors well know. It also undergoes frequent use as a rudey exclamation of horror, when something very bad or irritating happens.
