I know 100%, without a doubt and have verified it on countless occasions that I do have an asshole. Hell, I confirmed it a few minutes ago in the bathroom.
With that joke out of the way, does that make me an asshole. I have no clue, I am the same person online as I am offline. I am sure I have appeared to be an asshole to a lot of people and a great person to others. Either way, I aspire to use my asshole as it was intended then actually being perceived as one.
