First

A word that highly skilled internet commenters post on internet message boards to show their superior skills at being the first to comment on an article, blog post or other internet forum. Typically these people are highly skilled and successful individuals that are irresistible to members of the opposite sex.

Ian21 is always getting first on message boards, he is so cool, he owns PWE.

A term used to describe the first person to post a comment on a popular video, forum, or website. Usually used by little kids who think they are cool because they are the first of thousands to comment on something popular, when in reality no one really thinks its cool.

Comment 1: FIRST!!

Comment 2: Wow theres always someone that writes the first comment like that.
