bumback 

When using a friendship with drug addiction with no mullah. Drug Dealer bums off person he just sold drugs too. Most times it's not mentioned until the bum shorts your cash and drugs for their own personal gain. Late 30s and still not able to take care of himself without the stealing hand of "Sir Pinchalot", "Lilshort" and "The Subtractor".

Never has money or the amount paid for. Always short.

Derek bummed backed every day this week cause he got too high and forgot that money beats saying "I'll pay you back". Never pays you back. They be bumback and never pay back.
