Ear yogurt
When you let milk or some other dairy sit in your ear so long it turns into yogurt, and then your brain gets a migraine because it can’t handle the stink and the goo.
My ear was leaking yogurt for two days. I looked like a feral goat.
I tried to clean my ear with a cotton swab and it came out with a cheese-like substance. I cried.
I told my friend I had ear yogurt, and he said, 'You’re not funny. You’re gross.'
