This is a video from the channel of a professional YouTuber by the name of Ray William Johnson. In his videos, he reviews popular internet videos and sprinkles in his own jokes (usually dirty ;) In this particular episode, he reviews this video.

And that this attitude is usually what is conveyed to the masses (according to his most recent video, his channel is the most subscribed on YouTube).
