This wins the argument, sir: "Still you are a dick about it." Well done!
You skillfully kept the opponent in the dark about your game prowess and debating skill, and saved it all for the last, killing blow. Well done again!
Thank you for not using it upfront, as it would have had deprived us of a great discussion. Then again, if you would have had opened up the discussion with "You are a dick " instead of reliably sealing the discussion thusly, I would have similarly congratulate you for bringing novelle and progressively urban forms to the table.
