derived from pittsburghese slang word bars. when someone pwns or burns another's face, someone shouts " facebars!"

however, many people don't like the slang bars therefore ironically mock its use by using bars-bars, or megabars
person1: Your face is ugly
person2: oooh, bars!
person3: dude, youre still using bars???
person4: oooh, bars-bars! That's megabars!
