I was browsing this site for the first time today when I noticed these posts about Fire and realized that I was actually in several classes with him years ago when I was an undergraduate at UCF.
He is pretty much exactly what you would expect IRL. Fat and sloppy with acne, a bad hair cut, and a loud and nasally voice (one girl I was sitting next to once even had to once tell him that he talks too loud). I took one or two classes with him sophomore year but mainly tried to ignore him.
It wasn't until my senior year when I ended up in some research methods classes with him that I realized he posted on SA. I was talking to another girl in the class who I think he was stalking and he butted into the conversation with a joke that came right off the front page. I said, "I saw that on Something Awful" and he asked me "Do you have stairs" which I didn't know how to reply to and still don't. At that point I was extremely embarrassed that I had been on the same website as this guy, but I started paying attention to him more because of this. He had described himself as a popular poster and I told him I didn't participate in the forums (which was a lie but I didn't want to associate with the guy).
Anyway, he always used to get in conversations with people who obviously didn't want to have anything to do with him. One girl said he ended up talking to her for an hour while she was waiting for her boyfriend to pick her up and she ended up with a migraine for the rest of the day. He also was a huge pothead and showed up one day with a NORML t-shirt and a handkerchief around his neck one day to "show solidarity" for the cause.
I never interacted with him much for obvious reasons, but two things stand out to me. Once at the end of the term we all had to give presentations, and he actually filled his powerpoint with image macros and other crap from the presentation Lowtax had recently given at some college somewhere. It was really awkward and halfway through he started trying to explain why the image macros were funny since we all were ignoring him at that point.
Later, a few of us went to get some beers in between classes and he actually invited himself to come along -- just jumped in like a complete aspergers diagnosis and said "That sounds cool, see you all there!" and had one beer before noticing we were all ignoring him. When he left we all mentioned how annoying he was and how we couldn't stand him and I think that's pretty much what everyone thought about him.
Oh, he used to also always go on about how he was in some long distance relationship with some 38 year old woman in Tallahassee and once I heard him remark, "I've been around the block."
