The thing is, I discovered who it was just lately and I will tell you why.
When I extensively mocked the user and everyone was wondering why I am doing it saying that they never said that I started to believe that they actually never said that. After a while (well yes, I admit it took long) I decided to let it go but luckily it became a pillar of this forum.
A while later, namely recently the user pops up again to this forum and for my joy and astonishment he uses it. He uses it not as a joke, not as mockery, not as a repeated phrase on the forum. No, he uses it in its pure original form.
Can you imagine how happy I became? I literally gave up on figuring out who came with it until I saw it used again by its creator. I mentioned it when I saw it and I think only one member (a new legend) noticed my discovery.
I am sorry I will not reveal the name because many have already understood who I am aiming at.
