If there’s one rule you should remember when hitting the waves, make it this one.

Dropping in on someone is an almighty foul in surfing. It’s the best way to see a surfer lose his sunshine cool.

If someone is about to take off on a wave or is already riding it, do not enter the wave in front of them and cut off their ride.

Everyone is sure to commit this water crime a couple of times over the years. You just have to deal with the consequences and subsequent feelings of crappiness.

Not cool, man.
