can people please tell me what the following means please

PB , is there anymore i should know about cause im lost here lol

It means Productive Burp. Sometimes if you eat a bit too much, or too fast, you may have a tendency for the food to get stuck. Sometimes the PB will help relieve it. Another term you will see here is sliming. When something gets stuck, for some reason you will start producing a LOT of saliva, and since you are stuck it has no place to go but up and out. You don't get nauseated, but you do need to spit up. It will be mostly saliva with maybe a trace of what you have eaten. I don't do it often, but it helps to be near a bathroom. Eventually what you ate will go through, or at worst come up and you will feel better. I think I described PBs and sliming. Others may have more to add. This is a great place to ask questions and trade tips.

Good luck on your journey!
