burp
The release of gas that rises from the stomach_(organ) and out of the mouth by the organ being deflated when full of air and gas. Also known as belching, or in the scientific term eructation. Like a fart, a burp can have an odor; though there is much humor about it. This can occur from hunger, being full of food, eating fast, swallowing excess air, or certain drinks like wine or carbonated soda/anything fizzy that causes gas bubbles inside the stomach.
