Irony and Sarcasm are two concepts that can be used interchangeably. Others believe that these two concepts have unclear boundaries and only differ in different cultures or language communities. The object of Irony can be first person (speaker), second person (listener) or third person (person, thing, something), while the object of Sarcasm is the listener. In terms of aggressiveness, sarcasm can be divided into mild or severe levels. However, with Sarcasm, the aggression is always at its heaviest and most damaging. Sarcasm is also considered clearer, more specific, and more straightforward than Irony. According to the Theory of Superiority, humor is created by the speaker’s thought of being superior to others and from that thought the speaker creates sarcasm. According to the Theory of Incongruity, humor is created when the speaker creates an utterance that is different from the usual norm, so the meaning of the utterance is no longer the literal meaning but rather hidden meaning and usually humor is created from the implication of wanting to sarcasm a certain object.
