Kerozene: Meat makes farts stink waaaayyy worse than vegetables and fruits do. I am surprised I have to tell anyone this.
Also, vegetables and fruits only make the people who don't get enough fiber in their diet gaseous. Fiber is a type of carb.
Also, as the people who eat the most meat are fat rednecks , being a vegetarian or vegan is much cooler (and hotter.)

If you think vegetarian/vegan food is "terrible-tasting," you've never had any that was half-way decent. I've been a vegetarian for almost 4 years and I can assure you, I could make you a veggie chikin' and dumpings that would definitely change your mind. And I could kick your smelly, omnivorous arse.
