What is Dock A Sub?
(to dock a sub)
surfing term. a surfer desperately needing to take a dump while awaiting a wave, may choose to 'dock a sub' as opposed to paddling in to do his/her business.
ie: dude! the sets were coming in perfect about 1/4 mile offshore, and those eastside punks were way too close to my set - i docked a sub, caught that wave, and then sanchezzed them with it.
