I have three children 13/16 My own and 1-16 old stepson,all three boys..?

My 16 yr old stepson is very rude hateful and disrespectful to myself,his dad and my children.Example: I ask him to take the trash out..suddenly I'm a stupid b***h.I did not raise him so I can't take the fall for his actions.How would one handle this situation? This is a weekly battle and when he is'nt fighting w/ one of us he prefers to just be alone and not say anything at all.Hes almost a hermit except on weekends when he goes to his 'real moms' for the weekend where his GF also lives..HELP!
