Lahoy
A Lahoy is when you laugh so hard your brain explodes and a new laugh comes out like a high-pitched squeak. It happens when someone finishes your laugh and you’re stuck laughing at two things at once, which is pure agony and bliss.
My cousin laughed so hard during the dog’s faceplant into the cake that he made a Lahoy and cried at the same time.
At the funeral, my uncle started laughing and my aunt finished it off, and we all heard a Lahoy like a squirrel on a trampoline.
During the math test, my friend laughed so hard at my answer that he did a Lahoy and got a 2% on the test.
