A term for playing a nasty joke, or getting someone back for being a douchebag, while they are having sex, preferably while they yell and grunt/moan. Their mom is secretly dialed on facetime and all of a sudden they are getting some FaceTime with their mom.
Kyle was a nice and friendly Californian, and a generally well-respected young fellow. But, as he grew up he became somewhat of a large douchebag, showing his panties to everyone and ruining other people's lives. One day, Kyle took a particularly steamy poo in the bathroom, and, being a douchebag yelled; "I'm washing my face, cocksucker!", thinking he was hilarious. But, his one-night stand did not think his steamy-poop-taking-panty-showing-ass was so hilarious. Result; The Mother-Fucker.

Clean way of saying "motherfucker"
Usage in amongst K-pop fans most likely stems from entertainer Boom who used the phrase on episode 3 of 2PM's Idol Army.
Cast thought he said "motherfucker" in poor English and he stated he said "omma appa" and not a bad word.
