In a way it turns you on and you can't help but listen to it over and over and OVER.
The "hee hee ha ha HA HA HA" You find so amazing that when you hear this laugh it sends chills down your spine.
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"
