Oh.. Sorry. :/
I hate the slang term. It stems from when I worked at Burger King for the first time, and there was this manager that I hated (and she hated everybody), and she would run around saying "dude" all the time. Her voice was kind of annoying, like nails on a chalkboard (or that one woman from the tv show Friends, but without the funniness).
I don't hate you. If were to ever take up the use of the term "dude", you would be one of the best dudes I've ever had the pleasure of chatting on the Internet with (I can't say "met" because I haven't met you).
