I first came across this in a science fiction story some 65+ years ago (Silenzia, by Alan Nelson [F&SF, September 1953, p.61]): "...My name is Emmett Dugong. It is important that I talk to you..."] but that has nothing to do with the usage I'm thinking of now.
The Dugongs are gathering, out of sight. I have several; I want them to have their own spotlight, so I'll wait until they return from Calais to share them...
