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."
