Accidental Jerk
One who's personality lends itself to being bullish or blunt without considering the feelings of others. Initially, this type of person has no idea that others see him/her as a jerk due to obliviousness.
I really thought I was just providing my coworker pertinent information, but then I thought about the way I said it. I'm pretty sure I was an accidental jerk.
