I agree with the post on Jul 2, 2012 which I just saw today. If a girl is mean to a guy, the bitch needs to be punished so she'll stop. If she refuses to stop, he should leave the bitch. She doesn't deserve to have someone if she can't be nice. I had a girl who got mean with me but I didn't do anything. So she kept getting worse until I got mean back. Then she got nice and learned respected me.
To me, the meaning of just the chorus of this song is basically, tough love.
