4. Dumb-Ass Grammar Mistakes in "Educated" People - You do not use an apostrophe just because a word is plural. Ex. I have two cat's. You use it to show POSSESSION. Those are my cat's toys. Also, your and you're. Ex. Your thirty years old. FUCKTARD! There are many more that I can't think of off the top of my head.
5. Unnecessary Facebook Updates - I don't care if you are watching TV. I don't care if you are brushing your teeth. I don't care if you are watching a movie with your husband. I don't care about the minutia of your every-day life. That's why I will NEVER have a Twitter account. I should start announcing when I'm taking a crap, or masturbating. Facebook and Twitter are for narcissists. I especially hate the "feel sorry for me and tell me how wonderful I am" posts. Ex. "I hate that I am always alone." Get over yourself.
