There was that thread, which had a couple loudmouth trolls (who have since gone away, except I think one popped up for a few posts), and one of the loudmouths was being especially loud, and I said that they were an unknown quantity, and that's when they (2 of them) started deriding me, saying that my "thousands of posts don't mean anything" (paraphrased). It got more and more heated, and I believe (although I am too sluggish to dig it up) that "Fatty McFattypants" was a reference to my program director.
It spiralled from there, as these trolls fell away, and one guy ended up not getting ranked because of the way he insulted me (which I showed to my PD).
