Back before anyone was on this forum, but instead red dawn, h8tank, Russ, dennyfloss, Harvey, nowhereman, and elphenix (few others I don't remember off the top of my head, I was 17 at the time so it's been 13ish years) we had a different forum: one that would crash and lose all of our post counts and erase every forum.
This is where "first!" came from, as you were litterealy the first to start a thread on the sub forum.
Well, Neff figured that his post count was unfairly low and that this "first" bullshit was just that; so to boost his post count and be a satericall ass he posted his name over and over.
Thus posting to up one's post count is neffing.
I was MagnisKain at the time and my spelling was so poor that it was the basis of many complaints and the kindly elfinix would translate for everyone

I got banned but received amnisty some many years latter: though I still skirt the line heavily because of my winning personality. (I also grew up and stopped being a horrible relegious troll)
Also: obvious nestalgia troll is obvious.
