It is NOT just the possessive that's the problem.

"I would assume that 'bum wrap' refers to something that is 'packaged'"

I'm sorry to jump on you, but inventing a completely different etymology for a misspelled phrase to explain the mistake is just plain silly. If you're going to stick with your spelling, at least stick with the original meaning of the phrase and explain the misspelling. I'm pretty sure what happened here was that somebody in the past didn't understand what "rap" meant, decided to change it to "wrap" and made up a meaning -- this is *not* a separate phrase. FYI, OED says that "rap" means "a criminal accusation, charge" and that it frequently appears in the phrase "bum rap, a false charge, an undeserved punishment." And I can't find any mention of "bum wrap" in any legitimate source. I really hate it when people justify poor spelling with "it's colloquial" or "everybody's doing it." This is not the 18th century any more, and we should be happy about that!
