Fine - I am right. This argument is over. You need to shut up.
That's Okay - One of the most dangerous statements a women can make to a man. "That's okay" means she wants to think hard and long before deciding when and how you'll pay for your mistake.
Nothing - The calm before the storm. This means "Something" and you better be on your toes. Note: Arguments that start with "Nothing" usually end with "Fine" (See #1).
Five Minutes - If getting dressed, this means half an hour. (Don't be mad about this. It's the same definition for you when it's your turn to do some chores around the house.)
Thanks - A woman is thanking you. Do not question this or faint. Just say, "You're welcome," and let it go.
Loud Sigh - Not actually a word but rather a non-verbal statement often misunderstood by men. It means she thinks you are an idiot and wonders why she is standing here wasting her time arguing with you about "Nothing." (See #3)
Go Ahead - This is a dare, not permission. (Don't Do It!)
Don't worry about it, I got it - The second most dangerous statement a woman can make. It means that a woman has asked a man several times to do something and is now doing it herself. (This will result in you asking at a later date, "What's wrong?" For the woman's response, see #3.)
