Forum Addict 

These people originate on the Eastern coast of the USA. Often these individuals visit internet forums and post statements that make no sense and are of no relevance to the topic that is being discussed.
They have no control of their disorder and will stop at nothing to get another pointless sentance posted on some forum.

Quentin7234: Why did that guy just post on the forum that his dog doesn't eat sugar free biscuits, when this forum is about Battlefield 2?
Soothie1932: I think that guy is a "Forum Addict", he posts on average 43 times a day on this site and I am yet to see him make any sense.
Quentin7234: Well, I wish he would stop. He makes me uncomfortable.

Noun: A person who spends a ridiculous amount of time posting messages on forums. It is often speculated whether or not the average forum-addict has a job or a life outside of their respective forum.

Bob spends so much time on the internet, I fear he is becoming a forum-addict.
