chewing your food but spitting it out is kind of weird, and certainly some type of disorder, but it's not the same as vomiting. When you vomit, you lose the protein, water, and electrolytes your body needs, not to mention what it does to your insides. When you gnaw on junk food and spit it out, you are simply not eating the crap. I think it's great.
Oh, and to the guy that calls us a tubolard, I'm actually pretty lean (6-8% bodyfat). I run 75 miles a week, work out 4 days/week, and do another couple of hours of cardio in the gym. Sometimes, I also do a couple of 30 mile rides over hilly terrain during the week. So I'm not totally mentally weak--if I was, I wouldn't be able to get up at 4:30 AM to squeeze in a 12 mile run before work.
