Mr. MILF made me think of this--those who read a lot but speak relatively little know more words but maybe don't use them because they can't pronounce them or aren't sure if they can and want to spare themselves any humiliation. Those who don't read but talk a lot can pronounce a lot of words, but don't have a clue what they mean, so they usually end up using them anyways and make themselves look like fools by the small number of people that recognize both verbal forms and meanings of words.
