An after dinner surprise in which you expect a nice burp but end up with a little barf making its way up your esophagus thus leaving you with that horrible burning sensation. (Burp + Barf = Burf)

Get the burf mug.
The act of expelling an exceptionally acrid and heavy fart that feels hot in temperature, making only a slight "bfffff" sound as the bitter fumes leaves the anal cavity. Much more deadly and bitter than the average silent fart.
"Honey, you won't want to sit next me right now. This roasted garlic is making me burf."

"Sam was pissed because I burfed in his cube."

"My wife practically passed out from the burf I just left in the car."

According to my 3 yr old daughter, who came up with this word, it is what happens when you burp and barf a little at the same time.
