look up any word, like cunt:
When a person and/or animal belches into the orifice of another person and that person continues to swallow that burp. If lucky, it is followed by violent vomiting onto the partners face and lower extremities. On more than one occasion it will lead to a massive orgy
"my girlfriend offered to slob my donger, but i recommended a burpjob instead."

"while my baby sister was sleeping, i snuck in her crib and gave her a quick burpjob before i passed out."
