It's about a girl I was good friend with. During our friendship she was dating this guy that was a complete jerk to her. But still, she would always take him back. I was always wishing she would become dangerous and just slug the guy. Hence the lyrics in the chorus, "Danger Baby knock him out." I think a lot of girls and guys could relate to this song because a lot of people are in these kinds of relationships. It makes you wanna dance around while punching people who suck. lol
