I don't hate ketchup completely, I'm just a food "conservative". Dip your fries in ketchup, fine. Put it on burgers and hot dogs, fine. When people ruin steaks, brats, and fried chicken with ketchup, I just find it to be completely obscene and disgusting.
What annoys me more are the morons who smother everything on their plate with ranch dressing. Ranch on pizza, ranch on steak, ranch on hash browns, WHAT THE FUCK?! And I'm sorry, but ranch is just about the worst thing to put on a salad. Go with the bleu cheese, Russian, or a good vinaigrette.
Finally, what annoys me the most are the dickweeds who are bitching about this thread. This is the social forum, and this a completely appropriate topic for it.
