Sometimes, when food gets stuck you will do one of two things, slime or PB (productive burp). Sliming is pretty much what it sounds like. You basically have slime continually coming up your throat and into your mouth for a while. PB is a bit closer to vomiting, without the vomit. Basically, when you PB, the food that was stuck comes back up forcibly. But, you don't get all the nasty, acidy stuff that you would from normal vomiting.
