over poster 

Some one who takes up an entire page on a message board to get one point across. Will typically take up 15 minutes of your day with a useless post. The post usually pertains to how he is better than you at something, thus taking up an entire page to do so when he could write one sentence.

we are better than you.

Skip is a classic over poster, he has wasted hours of my time with those drawn out posts on the message board.
