Dumb Shit Intolerant Syndrome is when your brain explodes every time someone says something stupid and you literally lose it.
My cousin got D. S. I. when his friend said 'pizza is a vegetable.' I saw him throw a cheeseburger at a wall.
At lunch, my buddy screamed 'I hate math!' and I got D. S. I. and threw my soup at him.
My teacher said 'the moon is made of cheese' and I had to leave the room because of D. S. I.
