Someone devoid of actual training or expertise on a given subject, but watches Youtube all day so that they may interject fake expertise. Often they will watch what you are working on, run inside to watch a Youtube video, and then come out and try to act like they know about the subject. This often leads to improper use of words of phrases they know nothing about to look "cool" and knowledgeable.
These types are easily distinguished from the true "professionals" because they lack full understanding of the subject, practice improper use of the subject matter, and often run back and forth to the computer, and sometimes even bring it with them to "watch" and work.
Be sure to protect yourself from Youtube Hero's because they will likely mess up whatever they are working on and you will be caught holding the bill. They can be found in many areas but tend to favor Electronics, Computers, Car Audio, and Automotive Repair.

Nick was busy trying to get his stereo wired up yesterday when his room-mate came out trying to be a Youtube Hero. He heard us debating over which way would sound best and came out there and began talking out of his ass. We called him out and made him feel like a real dumb-ass. It's a good thing Nick didn't listen to him, because his amp would be toast right now.

The proccess by which a funny video, viral or not, is deemed unfunny by someone. This occurs when said person is told to watch a video by a freind, relative, the person who created the video, or some other person.
The reason it occurs is because the person being told to watch the vdeo is expecting something funny, which may not have been the case with the person who is telling the other person to watch the video (this person may have stumbled upon it, or if they created the video, overestimate how funny they really are)
Members of Youtube often destroy their chances of having their video go viral by saying things such as "omg go watch my video-it's so funny!" on the comments section of other viral videos-people are expecting something funny, and are let down when the video in question isn't as funny as they expected
Some videos are exempt from this effect, such as "HaHaHa" (the video of the laughing baby)

Editing of cartoons to make it be random and funny. Spongebob and King of the Hill appear to be pooped the most. Luigi and Mario are the mascots.

Where people ask for a opinion but denies that and says I do not need to change myself, and feels like they are above viewers
You Tuber: Hey guys and girls I need help what can I do to help my videos
Viewers: You should not be too hyper
YouTuber: That is what I am I am a hyper person (starts crying on camera for views)
This is YouTube syndrome
