Lactose intolerrhea
When your body gets so angry at milk that it throws a poop party in your intestines and you have to run to the bathroom faster than a kid on a sugar rush
I had a milkshake and my poop party started right away
My sister ate a piece of cheese and her whole house smelled like a poop party
I drank milk and I had to sprint to the bathroom like I was being chased by a dragon
