Surf with Responsibility and Respect
Dropping in on someone is when you get in the way of the surfer on the main "peak" of the wave. If a surfer is coming towards you, and you are on the "shoulder", you can ruin a wave for both you and the surfer, and is very dangerous and costly. This happens all the time, but mostly on accident. One simple thing to prevent this is to look for the surfers around you, and DON'T DROP IN ON SOMEONE.
This is one of the most talked about subjects with all surfers, and can be debated for hours upon hours.
