Limp Bizkit's Eightball: Yeah, you a hater, hater, hater
By Clammage
A person whose jealousy of another person success or achievements makes them verbally nit-pick any flaws no matter how small or just make up flaws in order to somehow try and belittle the successful person. The term is more often than not used improperly to title a person who simply does not like something or someone because it’s not what they are into.
Hater: there’s no way John could score a chick that hot, he’s gotta be paying her Dude: man, why do you have to be a straight up hater?

An overused word used by someone to describe another person that expresses a different opinion other than that of their own. This term is generally used by someone who can not intellectually respond to someone having a different opinion than that of their own and is thrown out as a last ditch effort to discredit the persons argument.
PERSON 1: You mean didn't vote for Barack Obama?! PERSON 2: No, I did not. In my opinion, I believe his politics are little too far left for me to feel comfortable voting for him. I'm sure he's a decent enough guy personally, but can't see him as my President. PERSON 1: You're just a hater.

A person who pretends to act happy for your successes than trash talks you behind your back. Someone who most likely dosen't have shit to work with and has to hate on people who move up in the world. This term could be used to describe anyone who hates on another person for 'good reasons. They will turn your good qualities around and make it look like something bad because they just arent happy with themselves and can't achieve anywhere near what you have.
Man, that Vitale is such a hater. He needs to stop drinkin that haterade and move on up in the world.
