When you are laughing soo hard that you look in the mirror or catch a glance at your reflection and the awkward and ugly face you make. Usually you laugh even harder for the ugly face that you HAVE to make when laughing that hard.
"Oh my God, when I saw that girl pee her pants on the dance floor I couldn't help but to laugh. Then, I realized it was my girlfriend and I started ugly laughing."

When someone tells a really long story that really has no point to it at all and at the end you make a little chuckle, giggle, or laugh out of courtesy.
Friends mom: *insert long pointless story here*
You: *chuckle*
Friend: That was such a couresy laugh
You: *chuckle*

A distinctive high-pitched squeal of a hyena laugh that only comes about when someone is high. This is completely independent of their regular 'un-high' laugh, and often sounds nothing like it. The more excited a stoner gets, the higher the pitch of the laugh. It is up for debate whether or not it's actually the weed that causes this girl-like giggle, or if it's more of a weed-cultural influence on stoners, much like a dialect or accent. ie. The more people who laugh like this while stoned, the more stoners will adopt said laugh, either consciously or sub-consciously.
My roommate's stoner laugh sounds like a shy Japanese girl watching cartoons while having an orgasm.

Nitrous oxide. Can be bought over the internet for 'culinary purposes'. A cheap drug that makes everything funnier, usually taken in a balloon so you get oxygen as well and don't die.

A Yandere Laugh Is When A Yandere Lets Out Her Insanity and After Their Evil Laughter They Will Feel Fine Again.

*Saku does a Yandere Laugh*
*She Becomes calm*
