Abecedarian abderites?

Is it ever effective to call a person an "abderite"? Anyone with abecedarian skills advanced enough to look up the word is probably not an abderite, while true abderites would just say "Thanks!" and move on, oblivious of the insult. Perhaps it's a word best kept for private delectation, uttered just out of the hearing of the person so described. Abderites. The place is crawling with 'em.
