Emo or punk rock band with a male lead singer with shoulder length black hair and two lip piercings and the video is him in a straight jacket either in a mental hospital or old folks home and the camera is mainly on him during the video can't think of how it goes or who sings it or the title that's all I can remember from it but has been bothering me for a few years it came out in the 2000's I know that!!

Is it Green Day- Basket Case. Try it. It might be it cause the lead singer had black hair and in that video he was playing as a lunatic.

Hope I helped!
