ELI5: What's that feeling of death in your chest that comes from eating thick foods like peanut butter too quickly?

That terrible feeling you're describing is your esophageal wall being pushed further than it's supposed to flex. 

This is because the food you're eating and the dry state of your esophagus means the food can't slide against the esophageal wall well enough to conform to your esophagus' shape.

Chew your food better, drink with your meals and take smaller bites to avoid this awful feeling.
