A person (or entity) who does what they have always done, whether or not it makes sense or is logical. A habitarian's favoriteexplanation is "because we've always done it that way." A habitarian does not only NOT think OUTSIDE the box--a habitarian does not think INSIDE the box, or anywhere else!
Friend: Why don't you pay your bills online--it's so much easier? Habitarian: That's the way I've always done it.
One who only eats happy meat. Often mistaken for a vegetarian, but these folks have no hard feelings about eating meat, as long as it's free-range, grass-fed, organic, happy meat.
Often broke, as happy meat tends to be expensive.
Karl: I never see you eat any meat, Sue, Are you a vegetarian?
Sue: Nah, I love meat too much to give it up completely. I just eat happy meat.
Karl: Oh. You're a happitarian. (Snorts in disgust)
Sue: That's right!
Karl: Well, I'm off to Burger King, where I can get a hot, juicy burger for pennies. No veg-meat for me.
A person who celebrates religious holidays (such as Christmas, Hanukkah, Easter, etc) despite a complete lack of religious beliefs.
Joe: "Hey I heard you're having people over for Hanukkah. I didn't know you were Jewish!"
Phil: "Oh we're not Jewish, we're doing it because we're holidarians."
