Mean Laugh

The Evil Laugh is a maniacal and loud laugh used by many villains. While evil laughter is certainty something occasionally indulged in real life, it is mainly a time tested staple of fiction. Evil laughs have been used for centuries in fiction to accentuate antagonists. Evil laughs can be traced back to some of the earliest works of fiction like ancient Athenian plays as signature pronouncements of malevolent intent. The basis of this act is to show the villain in question is not committing acts of evil incidentally or for purely practical reasons but instead signals the villain's sadism, relishing in the pain of others, or shows complete detachment from reality and further illustrate the villain's token insanity. The technique has worked so well that it now spans virtually all forms of fiction and has become second nature to nearly every villain of genuine malevolent intent or pronounced insanity.
