Protologisms
The word "protologism" is itself a protologism, a word newer than a neologism, and which is even less well established.

The article resides at Wiktionary. It is included here today because at this point I refuse to change the name of this site to "More Best of Wikipedia, Wictionary, and the Wikimedia Foundation"

By the way, the link points to some very funny material, in my view.
