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.
