H Boy (Mr. Light) 

H Boy is a youtuber known for his reaction videos which is usually in the form of tongue-in-cheek analyses. On top of this he also does Let's play videos of indie games.  The H Boy channel also used to consist of several random meme videos and the infamous "Slow and fast" series which was literally just a scene that was played slowly then quickly in quick sucession. Most videos on the H Boy channel with in this format until most of them were deleted (today, only two remain). However, what really caused the H boy channel to take of was when he played the disgusting video game known as Bubble Guts Simulator. Since then his channel has gone crazy.
