The act of expelling an exceptionally acrid and
heavy fart that feels hot in temperature, making only a slight "bfffff"

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."
