Sarcasm is the use of words usually used to either mock or annoy someone, or for humorous purposes.[1] Sarcasm may employ ambivalence,[2] although it is not necessarily ironic.[3] Most noticeable in spoken word, sarcasm is mainly distinguished by the inflection with which it is spoken[4] or, with an undercurrent of irony, by the extreme disproportion of the comment to the situation, and is largely context-dependent.[5]
