The first hater of a post that patronizes the lucky individual that comments on a post with "first". Though "firsting" is irritatingly common and a totally stupid practice to begin with, it does in turn lead to a multitude of "haters" commenting in "retaliation".
Hypocrite: Fuckin Firstfags! noone cares.
Intellectual: Ditto for you...
Hypocrite: You're probably a firstfag too.
Intellectual: If I am that makes you a First Hater.

When someone is confronted by criticism, but don't want to use it as advice to improve, they pull "The Hater Card" where they'll call you or others a hater, say the phrase "Haters gonna hate" or anything involving the word "Hater" as a means to avoid the criticism.
"Hey, although it is funny, try not to repeat the joke all that much. It'll become unfunny after a couple times."
"Haters gonna hate!"
"You're just going to pull The Hater Card because you don't like what I said? Fuck off."
"Haters gonna hate!"
