subs. (popular).—A colloquialism used both of men and things. Anything out of the common, or that conveys a warning; something wonderful or staggering; something to be avoided. Anything that causes surprise, wonder, fear, or indeed any uncommon emotion, is a CAUTION to this, that, or the other. At Oxford in 1865 it was employed to designate a ‘guy’ or ‘cure.’
