Maltz said he never heard the word QuchHa' for those Klingons. He said that must be a very old word or a taboo word that had gone out of fashion or something like that. He said the only word he knew for those afflicted Klingons was a word used mostly by children — HabwI' (one who is smooth) — but that maybe there was another word or a technical term that he just didn't know. He said that Klingons don't like to talk about this and maybe that's why he didn't know the terminology. (qepHom 2014)
