"The mother of the octuplets, you know, that one"
I came across a wonderful monicker in a comments blog and had to pass it on.
You're aware of this... strange woman who had octuplets a few weeks ago. The more we hear about her, the weirder it (she) gets. There is, however, no one name for her - just "the octuplets mom," etc.
In a comment to a story about her firing her free nurses, a reader called her the name I think will stick.
"Octopussy."
