What does bumming mean?
"Bumming" is the informal present participle and gerund of the verb "bum," and it covers two main everyday uses. The first is obtaining something by casual begging or borrowing without payment, as when someone is bumming a cigarette, bumming money, or bumming a ride from a friend; here it sits comfortably alongside synonyms like mooching, scrounging, and sponging. The second is passing time lazily or without purpose, most often in the fixed phrase "bumming around" — he spent the weekend bumming around the flat, doing nothing in particular. Both uses are firmly colloquial: the word belongs to conversation rather than formal prose. Regional caution matters, however. While Americans understand bumming primarily as mooching or idling, in British English the term doubles as vulgar slang for anal intercourse, so an innocent phrase like "bumming a fag" can land very differently depending on where it is said. The word derives from "bum," itself of obscure nineteenth-century American origin, possibly linked to German "Bummler," meaning a loafer.

Etymology of bumming
The word comes from "bum," an informal American English term attested from the mid-nineteenth century meaning a lazy person, vagrant, or loafer. Its further origin is uncertain; one widely cited theory links it to the German "Bummler" (an idler), though this connection is disputed. From the noun developed a verb meaning both to live as a vagrant or idle about, and to acquire something by begging or borrowing. In British English a separate, older vulgar sense of "bum" (the buttocks) produced the distinct sexual meaning of the verb.

In British English, "bumming" carries a vulgar sexual sense that can cause serious embarrassment if used innocently — speakers there usually prefer "cadging" or "scrounging" for the begging sense.
