Archaicexpression of shock or suprise. Derives from "God's wounds". As with similar archaisms, "Zwounds" is used in jocular contexts by tedious nerds with intellectual pretentions.
An exclamatory statement made when one is sarcastically surprised. Should be said with fingers on both hands extended out like spider legs and big blank exaggerated eyes like Johnny Depp ....perhaps while wearing a black eyeliner pencil moustache
