I've had them.. I'm sure we've all had them. Common for me and those around me who get them is getting really complacent and lazy in the swing.. Then when they arrive, you try to swing smooth to get rid of them but really, you're just compounding the issue. 2 things that helped me. Get really aggressive on some shots. Once you're back to your normal swing speed, place a headcover on the far side of the ball (or other balls, or a tee) and try to avoid hitting them with your club. Worked like a charm for me. No more hosel rockets.
