not just
beautiful, but mad
beautiful.
mad refers to the fact that when you see something or someone so
beautiful, it almost makes you mad that you didn't see them before or earlier.
mad is used to suggest that the beauty is not your ordinary beauty, but a beauty that is simply stunning and breathtaking.
ie. "yo, stop and check out that girl, she is
mad beautiful!"
ie. "the dance concert was unlike anything i have ever witnessed before. It was mad
beautiful; I was speechless."
