Hahgasm.
A laugh so strong it could knock out a bull and leave your ribs sore.
My mom said, 'I turned my TV on and my neighbor started singing,' and I had a hahgasm that made my neighbor stop singing.
When my teacher said, 'I failed the class and it’s not even my class,' I laughed so hard I fell out of my chair.
I saw a duck wearing a hat and had a hahgasm so big it made the duck look confused.
