Dropping in on another surfer's wave is the sport's greatest crime.
So when a Brazilian gatecrashed Kiwi Tim Thompson's ride on three straight barrels, he decided to do something about it.
In a video that has gone viral, Mr Thompson (inset) is seen rugby tackling the contemptuous Brazilian and wiping him out. "Let's just say my exit off the wave was either poorly timed or perfectly executed, depending on how you look at the situation," he wrote on gosurf.co.nz which first posted the video. The incident happened at the Mentawai Islands off Sumatra last month.
The video has earned widespread praise in the surfing community. Mr Thompson told Wide World of Sports that he felt what he did was fitting.
