Burn your face off

"I am so gonna burn your face off."

Burning your face off is an activity that involves an individual, usually a firebender, using fire to burn your face off. Most of the time, it was a very enjoyable activity for the person burning off your face. For you, not so much. Ozai was a big fan of burning off people's faces and he even performed this fun action on his son, Zuko.
