Someone who is technically a vegetarian in that they abstain from
meat, but who negates all the potential health benefits by eating mostly junk food. Many teenagers fall into this category. It makes being a "vegetarian" really easy, since you still get to
eat crap all the time, and still get the cool
hippie status that comes with vegetarianism.
"Hey, I've become a vegetarian, and I LOVE IT! I
never thought it would be so easy!"
"Wow, I could never live on whole wheat bread, cabbage soup and
beans."
"No, it's easy-potato chips and twinkies have no
meat in them!"
"Dude, you're just another junkitarian."
