Can Someone Explain What "PB" Means?

I see "PB" often on the board. I was hoping someone could tell me what it means.

Thanks!

Productive Burp... when food comes back up. Similar to vomiting but, the food doesn't come stomach.

What I understand it to mean is "Productive Burp"... as when a baby "spits-up"

I've only had one episode of what I would call a "productive burp" and that's what it was.... I was stuck and after a few minutes I 'spit-up'... wasn't violent like when I'm sick to my stomach and "vomit"... it just "came up" and then the stuck feeling was gone.
