You may be familiar with the term "sniglet," which refers to a word that doesn't appear in the dictionary, but should. This page from wikipedia gives examples, and you'll find additional examples by clicking on the external links at the bottom of the wikipedia page. I made one up and used it in a recent face-lift: Querritory: The amount of space in a query letter devoted to one subject.
We need to compile a dictionary of sniglets that deal with the writing business. Send as many as you like (as comments). Include a name if you want credit. Deadline: 5 PM Eastern, Saturday.
