gahg
the loud, silly laugh you make when something is so dumb it makes you want to punch the person who said it
My friend said he turned into a banana. I did a gahg so loud my neighbor asked if I was okay.
When my teacher said the sky is green, I did a gahg that made my dog roll on the floor.
I saw a man wearing a hat made of socks and did a gahg so hard I fell out of my chair.
