Something that attention-seeking children write as they desperately seek a feeling of self-worth for being the first to comment on a youtube video.

Used by the very first commenter on a blog or forum to show they beat everyone else to comment first

Apparently sought after position of being the first person to write on an online comment section, only to use the opportunity to write "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.

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.

SPAM commenting on anything with the incorrect assumption you are the first to contribute. Only comments which refer in some way to the subject commented on are real first comments. In other words it isn't a first post solely to add the word first.
