This glossary of surfing includes some of the extensive vocabulary used to describe various aspects of the sport of surfing as described in literature on the subject. In some cases terms have spread to a wider cultural use. These terms were originally coined by people who were directly involved in the sport of surfing.
Air/Aerial: Riding the board briefly into the air above the wave, landing back upon the wave, and continuing to ride 
Bail: To step off of the board in order to avoid being knocked off (a wipe out)
Bottom turn: The first turn at the bottom of the wave
Carve: Turns (often accentuated)
Caught inside: When a surfer is paddling out and cannot get past the breaking surf to the safer part of the ocean (the outside) in order to find a wave to ride 
Cross step: crossing one leg over the other across the board (usually to make it to the nose)
Cutback: A turn cutting back toward the breaking part of the wave
Drop in: Dropping into (engaging) the wave, most often as part of standing up
"To drop in": To take off on a wave that is already being ridden. Not a legitimate technique or manoeuvre. It is a serious breach of surfing etiquette, often done by ignorant kooks or snakes.
Duck dive: Pushing the board underwater, nose first, and diving under an oncoming wave instead of riding it
Fade: On take-off, aiming toward the breaking part of the wave, before turning sharply and surfing in the direction the wave is breaking
Fins-free snap (or "fins out"): A sharp turn where the surfboard's fins slide off the top of the wave
Floater: Riding up on the top of the breaking part of the wave, and coming down with it
Goofy foot: Surfing with the left foot on the back of board (less common than regular foot)
Hang Heels: Facing backwards and putting the surfers' heels out over the edge of a longboard
Hang-five/hang ten: Putting five or ten toes respectively over the nose of a longboard
Off the Top: A turn on the top of a wave, either sharp or carving
Pearl: Accidentally driving the nose of the board underwater, generally ending the ride
Pop-up: Going from lying on the board to standing, all in one jump
Pump: An up/down carving movement that generates speed along a wave
Re-entry: Hitting the lip vertically and re-reentering the wave in quick succession.
Regular/Natural foot: Surfing with the right foot on the back of the board
Rolling, Turtle Roll: Flipping a longboard up-side-down, nose first and pulling through a breaking or broken wave when paddling out to the line-up (a turtle roll is an alternative to a duck dive)
Smack the Lip / Hit the Lip: After performing a bottom turn, moving upwards to hit the peak of the wave, or area above the face of the wave.
Snaking, drop in on, cut off, or "burn": When a surfer who doesn't have the right of way steals a wave from another surfer by taking off in front of someone who is closer to the peak (this is considered inappropriate)
Snaking/Back-Paddling: Stealing a wave from another surfer by paddling around the person's back to get into the best position
Snap: A quick, sharp turn off the top of a wave
Soul arch: Arching the back to demonstrate casual confidence when riding a wave
Stall: Slowing down by shifting weight to the tail of the board or putting a hand in the water. Often used to stay in the tube during a tube ride
Switch-foot: Having equal ability to surf regular foot or goofy foot (i.e. left foot forward or right foot forward), like being ambidextrous
Take-off: The start of a ride
Tandem surfing: Two people riding one board. Usually the smaller person is balanced above (often held up above) the other person
Tube riding/Getting barreled: Riding inside the hollow curl of a wave
Over the falls: When a surfer falls off the board and the wave sucks him or her up in a circular motion along with the lip of the wave. Also referred to as the "wash cycle", being "pitched over" and being "sucked over"
Wipe out: Falling off, or being knocked off, the surfboard when riding a wave
Rag dolled: When underwater, the power of the wave can shake the surfer around as if he/she were a rag doll
Tombstone: When surfer is held underwater and tries to climb up their leash the board is straight up and down.
Hang loose: Generally means “chill,” “relax” or “be laid back. This message can be sent by raising a hand with the thumb and pinkie fingers up while the index, middle and ring fingers remain folded over the palm, then twisting the wrist back and forth as if waving goodbye, see shaka sign
Hodad: A nonsurfer who pretends to surf and frequents beaches with good surfing
