To swing away from the rock when all the holds are to one side of your body. Very common when climbing arĂȘte's.
To swing sideways out from the rock due to being off balance. Often occurs with a lie-back maneuver.
Occurs when a climber does not have an adequate grip with one side of the body and gravity forces a shift in balance that causes that part of the climber's body to swing away from the rock. The side of the body that does have a firm grasp acts like a hinge, and the climber swings out from the rock like a barn door opening. Good for a few chuckles for everyone except the aforementioned climber.
To fall off a route, first losing contact on one side and swinging off like a door opening on its hinge.
(n) an off balance move that causes a climber to pivot on two points of contact making it more difficult to cling to the rock
To swing round, away from the rock, when all your holds are on one side of your body; especially likely when laybacking an arĂȘte. Usually experienced where the hands and feet are on the same vertical surface, or the hands are holding something beyond the feet.
