A burp which regurgitates an unknown mysterious substance; usually something you have just eaten or imbibed.

It can be a rather disconcerting process but on the whole there is nothing to be concerned about.

This is not to be mistaken with throwing up a little bit in your mouth as this is not an unpleasant experience, rather it can be quite enjoyable!
Steve: "Hey Pete, I have just enjoyed a rather nice cheese and pickle sandwich. All of a sudden I just burped and it feels like I just regurgitated some undigested sandwich!"

Pete: "Hey don't worry Steve, you just did what is commonly known as a regurgiburp! Enjoy the ride dude!"

Steve: "... if you say so! You have issues!"

Pete: "Dude, its natural!"
