bum sandwich

Made solely from plain white bread and one slice of processed cheese, it is typically a sandwich eaten by someone who has hit rock bottom. The only additional ingredient allowed beyond bread and processed cheese is hot sauce; however, this changes the title to "spicy bum sandwich". Other abbreviations include: Hot bum sandwich (microwaved), Toasted bum sandwich (toasted white bread) or the famous one slice folded over version "the bum foldwich".

Something that is already shitty but can get considerably more shitty. A Bum Sandwich has the ability to produce its own shit and thus is worse than a shit sandwhich. It can fart or shit directly in your face.

Remember not to eat a Bum Sandwich, they cause bad breath.
