An emotion fiddler is someone who plays with people's emotions. They can cause great anger using the power of their mind. Most beleive them to be fictional , but others beleive they are existant.
When you get completely naked and sit indian style on your girlfriends chest while she pretends to play your flaccid gummy dick as a fiddle while chugging soy sauce.
