Third nipple

It's been asked before about the nubbin label. (I guess it rubs people funny! Har har!) I think you could say it's a third nipplish post of sorts. Like not really a proper post, but just an extra lil somethin' somethin'. The internet offers this definition:

nub·bin n.
1. A small stunted ear of corn.
2. A small stunted or projecting part.

Being a long time Dooce reader, I actually stole this label from her. So there you have it!
