Shoulder surfing (surfing)
In surfing, shoulder surfing refers to shoulder hopping. Shoulder hoppers do not take off on the critical part of the wave where there is a need for a high level of skill, but take off further down the line. They are often regarded as annoying by more experienced surfers because shoulder hoppers will sometimes drop in on a surfer already riding the wave - which breaches surfing etiquette of "first on wave has right of way". Southern California early eighties band the Surf Punks performed a song called Shoulder Hopper for their album My Beach.
