GAHGAHGAH
you shout GAHGAHGAH when someone says something so silly it makes you feel like you’re going to die from laughing
My cousin said 'I can talk to dolphins' and I GAHGAHGAH’d him so hard he cried
When my teacher said 'I can eat 10 hot dogs in one sitting' I GAHGAHGAH’d her so loud the lights went out
My friend said 'I can fly' and I GAHGAHGAH’d him until he fell out of the window
