No real meaning, but on usage one may receive an image of the subject (the person who you are using the cuss on) sucking on the left breast of an old lardy woman, something which presumably the subject would rather not have people around him thinking about himself.
Literal example:

"The other day I sucked on the left breast of an old lardy woman"

"Fuck, I was gunna cuss you but what you've done means that you actually ARE a tit-munster"
