I was about business, now it's giving villains the bizness!

I'm a easy going guy, but my buddy is a beast.

I hang with the A-list, but I don't get no respect.

Maybe it's my bad rep, but hey why single me out?

you got a guy who's a lush, a guy in a rush, a guy who rusts,

and a who points fingers and fuss.

Who Am I?
