The Sackless Boob

My five year-old granddaughter, Audrey, was sitting at the table with me coloring while I was writing blogs on my laptop when she accidentally broke off the tip of her crayon.

I knew she didn't know about the sharpener at the back of the box, so I asked her if I could see her crayon box.

"It's my crayon box," she informed me.

"I know. I just want to see it."

"Well, it's mine."

"Can I just see it?"

We bantered back and forth until finally I said, "Never mind, Audrey." I then got up to put on some water for the spaghetti I was making.

Sensing that she had upset me (she didn't, but she's empathetic and I knew that my leaving the table would cause her to think she had), she arose from the table and walked over to where her mother was sitting.

"Sorry, Mom (yeah, she apologized to her mother; not to me), "I'm just a sackless boob."

Now here's my question – I have never heard this phrase spoken before – did she make it up or did she hear it on The Simpsons (her dad's favorite show)?
