traäzik ulalath: literally “stony ignorance”, (or for the convenience of Tellurian readers, “stone stupid”, even though the backing metaphor is entirely different), the very special kind of stupidity self-inflicted by and on the extremely loyal, be it to contract, person, cause, or necessity, characterized by making extreme deeds and ludicrous plans appear logical, sensible, and sane.

See azkith, “loyalty”, from azik “stone” + ankithel “emotion, passion”.

(Incidentally, for the MLP:FiM watchers among my readers, Tanks for the Memories is pretty much exactly what an episode of traäzik ulalath looks like.)
