(Said by my cuzzo in anger) It means that you can do something so low as to suck somebodys fart because that would value your time more than sitting here bothering me.
A toe rag was originally a foot wrapping used, since mediaeval times up until the mid-nineteenth century, to protect the foot from chafing by boots or shoes. As these were, quite literally, rags they weren’t usually washed, and so with use they became very smelly until they were thrown away. Because of the similarity in smell, toe rag also became the name applied to dried, salted cod or other things with a strong, unpleasant, fishy smell. It didn’t take that long before the name was applied to someone who was an obnoxious, unpleasant OIC.
