first commenter 

Usually 7-12 year olds on YouTube who think that commenting "first", "early", "notification squad" on a new video is going to make them cool and popular, when it, in fact, does the complete opposite.

First Commenter: "FIRST!!11!!!"
More Mature People: "Please shut the fuck up with your "first" crap."

first comment whore 

Noun: Any of the species of assholes that feel the need to get the first comment on something as if it actually meant something. These illiterate jackoffs can usually be found trolling Youtube, flash game websites, Myspace/Facebook, blogs, and other places where comments are enabled. There are rumors that these trolls can type faster than they can masturbate, however this is not true.

FCW: first

You: Nobody gives a shit. Fuck off

FCW: if u dont give a shit than y did u comment back

You: You are a donkey-fucker. Go scribble 'first' on the inside of some donkey's sexual organs you cock-smoking first comment whore

FCW: ur a nooob

You: *suicide*
