Created by a Northern Virginian in the late 1970s by combining
tired and horked to create a word that means exasperated, exhausted, frustrated, and annoyed. Word was created as part of a class project to create new or combination words in the same manner as those found in the Jabberwocky poem.
The phrase caught on and spread throughout several Northern VA schools in the late 70s and early 80s. Frequent relocation of
people to and from the area is the probable cause of the continued spread of the phrase. The phrase, by the early 80s, had evolved to generally
mean mad or angry - not necessarily exasperated and
tired.
Popular variation in the 80s was "totally torked".
Possible variation or parallel development is "I am torqued" which is
based upon "torqued" which means something that that is twisted, possibly to the point of being under stress though over tightening.
