2.
Pretty much someone with no life who goes around commenting retarded, no way constructed often racist comments on youtube videos. If someone says "That video was bad becuase.... blah blah.... try to have better lighting next time." Thats not a hater. If a video actually does suck, saying that it's bad doesn't make you a hater at all, but its when your video isn't that bad that these get out of hand. Youtube haters also usually spell like my dog... when she was in her mom's belly.

A YouTuber who leaves rude, mean, and/or degrading comments on other YouTuber's videos and/or profiles that are, in no way, constructive.
You just left me a comment that says "Your video's stupid...", you're such a YouTube hater!

Term used by Youtube drama/attention whores to describe people who criticize their videos or don't give them 5 stars. A sad and tired retort used by people whom are very butthurt because they didn't get the fawning admiration they were so pathetically seeking.
Prima - "I thought it could have been better"
Secunda - "ZOMG!!! you are an YouTube hater!!!one11!!"
