Laughter that sounds similar to that of The Joker. The laughter should only be used upon commiting an act of indecency. Such as: Physical harm inflicted upon yourself or others, an epiphany that revolves around chaos, destruction of public property, or a sight of morbid hilarity.
Should also be used in public to either irritate people to the brink of insanity, or to discomfort insecure people who will look at themselves upon hearing laughter.
The laugh can be:
a low pitch "Ho-ho-ha-ha"
a half sob, half laugh "A-ha-ha-he-he-hew-hew"
a high pitch "A-HE-HE-HE-HA-HA"
a screaming "HAHAHAHAHAHAHA"
