After a short version of the video above was posted as a Vine, it went viral, and “RIP Billy” became a Twitter trend. The Vine showed two high school boys squaring up to each other. One then takes things a step further by punching his foe right in the face, knocking him to the floor.
The weirdest thing is how the teacher just sits there, doing nothing.
Now, this 19-second YouTube video adds context Vine, which was removed from the 6-second-video-sharing site. We see the eventual punching victim hurl an object at the puncher, who then confronts him. The setting appears to be a high school science lab.
