Well, I hate to get violent here, but the best way to make a screener back off a little bit, is lower your shoulder into his sternum, knock him on the floor, it still counts as only one foul. But the bastard won't set a screen that way again.
Same as getting beat on the baseline D. Throw a hip into the baseline driver and send him into the student section. It's still just one foul. He won't drive the base line again.
