fuddism 

A Fuddism is a word or phrase you try to say normally, but comes out like you have a speech impediment, like Elmer Fudd. This might occur when you are looking at one word and trying to say another, or it might just be an odd combination of words that acts similar to a tongue twister. It is uniquely a Fuddism if the ‘W’ sound is used.
