A wet burp is a slang term for a burp where small amounts of liquid are regurgitated. It is similar to vomiting—one who experiences a wet burp often has an acidic/burning sensation in the mouth, which can be displeasurable.
According to Charles Bourland, a consultant for the NASA Food Technology Commercial Space Center, if one burps in outer space, it is usually wet because the liquid and gas do not separate in the stomach like they do on Earth.
