A person who drinks milk and yoghurt like it's a religion, even when their body turns into a fart factory. They're too cheap to buy medicine, so they just suffer and keep chugging.

My mom eats yoghurt for lunch. She says it's the only thing that keeps her sane.
He drinks milk like it's water. His pants are now a prison for his guts.
