I am definitely put off by bad titling in anything. I refused to see Intolerable Cruelty in theatres for that reason, and likewise I will refuse to read any fic that follows that pattern. There are many stale quagmires of bad titling one can fall into, but that? Is the worst. 'Intolerable Cruelty', 'Dark Passions', 'Tantalizing Lies' - no. (Though I've never actually seen a book with a really gross, laughable title. Movies and fic seem to be the biggest culprits here.)

'Untitled', to me, signifies a short, throwaway story, but that doesn't mean bad quality. I will be more likely to admire an untitled story than something that sounds like it should be prefaced with the words 'Monty Python'.
