Half Nelson offers an opportunity to marvel, once again, at the dazzling talent of Ryan Gosling for playing young men as believable as they are psychologically trip-wired. (source)
Though familiar with the noun, I have never seen "tripwire" used as a verb. Also I am not able to find the verb form in any dictionaries. Here the quoted usage is figurative, which is even rarer, if not the writer's own invention. Google Books searches return several hundreds results for the exact word "trip-wired", most of which though are about land mines or traps. What exactly does the word in the quoted line mean? "Wired", "geared", "equipped", "disposed", "inclined", or "triggered"?
