'an a** or an elbow'

Posted by SR on February 09, 2005

My daughter was complaining about something last evening, and I said to her, "You know, you're never without an a** or an elbow."
Once I had said it, I realized my own mother used to say that to me some years ago when I was growing up in Ireland. Is it/ was it a popoular saying meaning to complain a lot?
