A person that makes it a sport to get a comment into the highest rated comment section on youtube by posting a message that adds nothing to the video but is guaranteed to receive many thumbs up. Examples include, but are not limited to:
1) abusing an old and tired internet meme
2) using phrases that begin with "Thumbs up if..."
3) if the video was bad, pointing out that watching the video was a waste of time
4) squeezing Justin Bieber into the formula
1) DAMN NATURE, YOU SCARY
2) Thumbs up if you've ever taken a shit
3) Well that's 5 seconds of my life I'll never get back!
4) Now lets try that with Justin Bieber!
