I think we have to eliminate food freakisms entirely, because everyone has them to various extents. Me, I'm a picky eater, for instance. My brother puts ketchup on his green peas. My mother refuses to eat beets, and yet, she's the one who prepares them. My father enjoys ketchup with scrambled eggs and vinegar on his french fries.

So we'll exclude the food freakisms for now. The nervous habits are also just that -- nervous habits. However, I'm tempted to say the running-fingers-through-hair might be your freakish thing.
