A man who's insulting and offensive to everybody, and acts very casual about it. He probably had some traumatic experience that causes him to be this way, but he won't talk about it. A real badass in any situation, always has a plan. On the outside, he may be rough and even violent, but has a heart of gold; you just have to dig deep down for it.

Abbreviation for “Dude Arguing Online”.
