The phrase means literally what it says, the word "off" can be replaced with the word "without". Off is used here in the same sense as one would use getting off a bus that is, physically getting out of it. The phrase is specifically used to show that someone or thing is being cut out (or off). The literary origin is speculated to be from the medieval American history.
