1. Being vegetarian. Why don't you just say you're "happiness-disabled" instead of vegetarian.
2. Being left-handed. Life is rough for you and I'm sorry.
3. People who can't curl their tongue. No one in the world cares about this but there's a slight sense of comradery when you're with a group of people and you find out you are in the tongue-curling club.
Actually i don't have anymore. I just wanted to make fun of you vegetarians.
