You are

 Supposed to be a grown ass man actin like you wanna fight me 

I turn around

 You standing on my heels running me down fo what reason 

A black man can't wait

 To tear me down 

Because a black man

 Certainly called me a bald headed bitch on the bus 

Not only

 Call him a black bitch right why stop there 

Why not a black bald headed bitch or you black monkey 

I don't want to have to

 Call any man a bitch 

If he was a white man

 I might of said white bitch 

If he was a yellow man

 I probably wouldn't of said yellow bitch 

I wanted to call him

 A black bitch but couldn't fix my mouth to say it a split second decision in my mind 

But if that's how you

 Present yourself 

Its also sad to have to

 Refer to a man as a bitch
