"Miss Shrunky Dunk" sounds a tad unusual, doesn't it?
A few weeks back I saw a friend whom I hadn't seen in a couple of weeks. In those couple of weeks I'd lost a few pounds and her response upon seeing me was "OMG! Look at Miss Shrunky Dunk here!"
It stuck. And, I like it.
It implies shrinking, which is what I hope to continue to do.
