ugly laugh

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."

Stoner Laugh

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.

Taco Laugh

When one laughs so hard that their mouth goes very wide open and the corners of their lips become highly rounded - so that when viewed side-on, their lips literally take the shape of a taco shell.

If you manage to get a side-on image of your friends taco laughing, it is guaranteed to become a crowning meme in the group.
Me: Why did the chicken cross the road?
Friend: I don't know, why did the chicken cross the road?
Me: TO GET TO THE OTHER SIDE!!!!!!!!

Me: -Takes picture, posts it on group chat-
Friend: Oh no did you take a picture of me taco laughing?

Me: Yup, that's why it's called the taco laugh!!!
