Definition: This noun refers to the trough (bottom curve) of a very hollow wave. The pit is where the most critical of bottom turns must be completed and where a surfer must navigate in order to set his/her line through the tube. the pit is normally the deepest (or closest to the breaking lip and whitewater)that a surfer can be without being sucked up by the barrel. Surfers can also (when the tern is used as a verb) be pitted or get pitted when surfing.
Also Known As: gut, innards
