 It's when a user posts in an old forum. It's greatly frowned upon and shoudn't be commited.

whenever someone posts on a old post it causes it to go up all the way the the front page.

 Necro meant dead in ancient Greece. As mentioned above it is when some posts on an old thread with little to no substance that contributes the thread. That the thread was better off dead. Example is posting on a thread from sixteen years ago.
