I just used the word "frothy" in a new and surprising way (for me). "Can we put a rush on this? So-and-so is starting to get frothy."
Even though it is an existing word, it takes on a whole new level of, well...froth when used to describe the lather* that So-and-so is getting herself in while she waits for the object in question. I'm not sure that froth/frothy/frothing is generally used in this alternative context, but the person who I was speaking to at the time knew *exactly* what I meant. Add that to the Bectionary!
Interesting to note: I usually use "frothy" to describe big wedding dresses and fancy, blended cocktails.
*Oooh! Lather is a good one, too.
