surfing
Surfing is the term is used for a surface water sport in which the person surfing moves along the face of a breaking ocean wave (the "surf"). However, surfing is not restricted to saltwater, but can sometimes take place on rivers, using a standing wave.
The main use of the word "surfing" is for riding waves using a board on which the surfer stands. Other forms include bodyboarding, in which the individual riding the wave only partly raises his upper body from the board surface, and from bodysurfing, where no board at all is used
