A form of sarcasm used on YouTube in which the tags for a particular video seem to be unrelated that video, but the tags reveal an underlying message about the video. An example of this would be a video about college football referees screwing up a field goal call, with tags such as "Ray Charles" and "Stevie Wonder". Charles and Wonder are two blind musicians, thus suggesting that the referees are blind.
YouTuber #1: What's with all of those Ray Charles videos in the related videos?
YouTuber #2: Whoever uploaded this video tagged a bunch of blind people.
YouTuber #3: The ref is blind! I love Tubecasm!
