a bum crumb ass nigga is that one nigga who thinks they the shit but actually fucken ass at everything they do, video games, school, and hell, even making friends. You can tell if somebody’s a bum crumb ass nigga if they wear their beanie at the top of their head with the top of the beanie all raggy n shit. They also wear baseball caps backwards and sitting on the top of their head so that they seem to have a tall head, bc their heads are small and their brains are small, and end up looking extra retarded.

Old American hobo slang, derogatory for a fellow hobo of really bad character.

The word "bum" is old hobo jargon for a hobo who don't do any honest work for his food and shelter, and as a such is poisoning the towns and communities for hobos with well intention.
"crumbs" is hobo slang for lice, which is something you for obvious reasons don't want to catch, especially if you are a hobo with enough concerns already in regards to everyday survival.

When the two traits are combined you get a character you certainly don't want to be a travel companion with, A person who will leech off your efforts and only give you a head-lice infection in return.
-Cigarette in Emperor of the North was a crumb-bum he just tagged along with A No. 1 and was of no help when it counted.

-Don't be such a crumb-bum take a shower and get a job!

-The modern elite are crumb-bums, living off the spoils of a once rich society they fail to maintain.

A term of utter contempt for a man without any honor, scruples or roots for the future. A man with no respect for women and no financial stability. A man who schemes to gleam. A man who “acts as if.” A poser; a wankster. A hustler with no heart. A man who shines cause his girl is minted; douche.
