This archaic, endangered and highly regional English word simply must be brought into common parlance. It's just too valuable to disappear. "Quanked - overpowered by fatigue" source: Dartnell and Goddard (1893). A glossary of Words Used in the County of Wiltshire (in Kacirk's Word Museum). It's just so useful when the more confronting word and its participles are normally used. "I'm completely quanked" sounds just so right. "I'm completely quanking quanked". Pithy, two participles from the same root (pun intended).
Well, off to bed now, or I'll be too quanked in the morning to be any good to anybody.
