Adjective: A descriptive term to be used in describing something as pertaining to having qualities of a dude. However, as opposed to manly, the purpose of dudely is to be used offensively as a descriptive term for a female who is particularly fat or ugly and has qualities to her looks that might make one so confused as to think she was in fact a dude.
"Aww fuck, it's Olga... She's so dudely. I throw up in my mouth everytime I see her. It's like a butterface, except the rest of her is awful, too!"

You're Mr. Lebowski. I'm the Dude, so that's what you call me. Or maybe His Dudeness, or Duder, or El Duderino if you're not into the whole brevity thing.
