outspoken
The nice way to call someone a complete dick, someone who's being tactless or maybe a tad too truthful. Por ejemplo:
Girl: Wanna go out sometime?

Complete Dick: No. You're hideous. In fact, I'd mistake you for a failed abortion if I didn't know your mom was a pro-lifer.

Girl: You're a complete dick!

Complete Dick's Friend: No, he's just very...outspoken.
