'Knockout King' is a frightening phenomenon that has claimed lives across the country as teenagers and young adults seek out sick thrills. In the planned attacks, a group will appoint a leader and then choose a defenceless victim at random. The leader then steps up to the victim and punches them out cold.

Many believe the phenomenon is driven by a thirst for attention. It is well known that juveniles don't think out consequences clearly, they see something on YouTube and say, “I want to get that sort of attention, too.” They don't think about the person they're attacking maybe hitting their head.’
One recent example that sparked outrage across the country was footage that surfaced from a Chicago train station.

Knockout King was a group of young males were seen following an elderly homeless man, before punching him in the face and knocking him out. The youths then jumped on a train, laughing at their sickening exploits.

The horrific video received a quarter of a million views within two days after it was posted on a hip hop website.

The nestle knockout is when you fist a sexual partner in the ass while punching them in the face with the other hand. It is usually performed while having sex in the doggy style position.

The word was first used in the main stream by comedian Bill Dawes in a stand up routine.
So I put a finger in her butt, and she was like: "Umm, what are you doing?!? Put your whole fist in there! And punch me in the face! I want the whole Nestle Knockout!!!"

\"The so-called \"California Knockout,\" a person holds his breath for 10 seconds to get light-headed, after which a pal squeezes his neck to put him out (unconscious).\"

It\'s some kind of wacky \"trip\" or \"high\" inducing maneuver. Commonly practiced by stupid teenagers. It kills brain cells.
