What does frontside mean?
Backside and frontside refer to the way a surfer is facing relative to a wave. If a surfer is facing toward the wave, he is surfing “frontside”. IE, the wave is at his front. Check out Stick Man…
“Regular” means his stance: left foot forward. If he were goofy (right foot forward) going the same way along the wave, he’d be backside, with the wave at his back.
