It started with the occasional bit of ironic emphasis while telling stories.  Something something something, bitch."  Then it became something closer to a running joke, but without the humor, or even hint of humor.  A verbal tick almost. Nothing meant by it, which isn't a defense at all, since why something if it means nothing?  Worse, why say something if it means nothing but will be perceived as meaning something, something which you'd not want people to thick you mean?  So, I cut the bitches out of my diet.

I wonder what else there is in speech which "means nothing" to the speaker, but which others hear as meaning something.  I wonder what the cost is of those words.
