Asshattery Rule #1
Your opponent's grammar is the most important part of his post. Always attack it rather than the content of the post.
Asshattery Rule #2
For every statistic you cite, multiply or divide it by three in a way that makes your argument more believable.
Asshattery Rule #3
Always boast about your income, education, and number of girlfriends. You are a rich Harvard-graduate pimp, and do not let anyone forget.
Asshattery Rule #4
You are always the victor of every argument in which you partake without any exceptions. For every repeat debate partner you have, bring up the fact that you kicked his ass in your previous argument(s).
Asshattery Rule #5
As soon as you register on a forum, you are more important than the board’s founder is, and you must act like it at all times.
Asshattery Rule #6
Make generous use of the words “fascist” and “Nazi.”
Asshattery Rule #7
One user name is never enough. Create at least five for every message board at which you post.
Asshattery Rule #8
There are twenty-four hours in a day. If you cannot make at least one post per hour every day, you have failed.
Asshattery Rule #9
It is important to stretch the definitions certain logical fallacies (ad hominem, ad populum, etc.) to fit any situation. Refrain from describing how the statement is fallacious and just call out a random logical fallacy, preferably the Latin name; it makes you sound smarter.
Asshattery Rule #10
If your peers decide to adhere to these rules as well, ridicule them and deny you have followed the rules yourself.
EDIT: And Asshattery comes from the word asshat, a less severe form of asshole.
