Geek boys seem to be the ones to make a really big deal out of it...although yeah, I've known some geek girls who've bragged about living on nothing but bacon and Doritos. I think wholesale rejection of veggies is a machismo thing for a lot of geeks, male and female. I really don't get how they don't end up with malnutrition. Maybe some of them do.

I do know people who only have one or two vegetables that they'll eat, but a lot of that is not really being exposed to vegetables (or vegetables cooked well) growing up.
