"I ain't even mad cuz..."

My favorite phrase, currently, at least as phrases from the hip-hop and rap world go.... is the title of this post.

"I ain't even mad."

Let's dissect. First of all, you're not mad. But rather than simply being 'not mad', you're not even mad. There's a reason why you could be mad, and yet, you are not. Why not? Because something better exists. And as long as this better thing exists, you have no reason in the world to be even slightly upset.

Does this make sense to you? Perhaps some examples will help.

"This girl said she wasn't interested, and she was so harsh. but I ain't even mad cuz she's not as cute as the girl i'm taking out to dinner next week."

See? No worries there. girl A is easily replaced by girl B, who is also much better.
Or even,

"My girl said she doesn't want to stay the night, but I ain't even mad cuz she just treats me so nice, I know it won't be forever."

"I ain't even mad" indicates a person who is wise enough to recognize value and prioritize desires based on that value. And whom is unfazed by minor inconveniences because they realize the quality of their life is really good and untarnished remains that positive belief.
