Aparentemente, o termo foi cunhado por Arlen Riley Wilson , esposa de Robert Anton Wilson. De esta entrevista com a RAW :
I coined the term spokesentities, because I was in a restaurant in Boulder, and they gave me a card, to evaluate the food, the service, this that and the other, and they asked me to evaluate the waitperson. And it asks for comments. So I wrote in the comments, I wrote, "Waitperson stinks of human chauvinism. Change it to waitentity at once!" And I signed it "animal lover."
And then I started using that, then, and my wife, Arlen, changed it to waitcritter.. Waitcritter, Congresscritter; clergycritter… I wouldn't want a clergy-critter getting into my house. And it changes the whole abortion debate. Now all they can argue about is what point after the penetration of the ovum by the sperm does the resultant become a critter? And when does it attain critterhood?
