From luchawiki.org - I'll be cleaning this up later.
Candado - [padlock] Headlock.
Candado Invertido - Front facelock.
Casita - Stepover armbar with a rolling cradle. Also known as La Magistral, but that term is never used in Mexico and I have only seen it being used in Japan. Allegedly invented by Pepe Casas.
Campana - Pendulum Submission Hold, used by Halloween and Bull Nakano among others.
Cangrejo - Crab, mostly a Boston Crab, but it's a generic term. A half Boston crab is known as "medio cangrejo" (half crab), and a Scorpion Deathlock is often called "Cangrejo Japonés".
Cavernaria - Submission hold in which a sitting attacker places his knees on the lower back of a kneeling opponent, and pulls him back with a chinlock or from the hair. Invented by Cavernario Galindo.
Cerrajera - Standing octopus hold with a "palanca" (armlock). Invented by Enrique Llanes.
Cristo - Sort of a suspsended full nelson hold.
Crotch - Also crotch slam or "crochito". Throws, like a bodyslam or a powerslam. This is a wrong, nonsensical term made-up by the commentators.
Cruceta - Figure-four leglock. Also referred to as "La Cruceta del Enfermero" since El Enfermero made it popular in Mexico.
Desnucadora - Literally, neckbreaker. Any powerbomb move is a desnucadora.
Escorpión - Scorpion (deathlock) aka sharpshooter. Also called Cangrejo Japonés

Fuerza Punt - A term born in the highspots.com lucha libre boards and designed to describe Fuerza Guerrera's inverted atomic drop.
Gory Special - Back-to-back backbreaker submission, invented by Gory Guerrero.
Guillotina - [Guillotine] A legdrop.
Huracanrana/Huracarrana - A frankensteiner finishing in a double leg cradle (rana). Invented by Huracán Ramírez. The only two correct spellings are the ones mentioned here, all other variations are misspellings.
Lazo - Lariat.
Martinete - Piledriver, usually a Tombstone piledriver. This move is banned in Mexico as it's lethal, and EVERYBODY (and I mean EVERYBODY) sells it like death (well, except when somebody screws up and uses it by mistake, i.e. Dandy vs. Antifaz hair vs. mask match).
Mortal - Any 360 or 180 flip (a moonsault, a somersault bodyblock, etc.)
Nudo - [Knot] Basically, any submission in which the attacker ties his opponent's legs and/or arms in a knot.
Nudo Lagunero - Sometimes, images explain things better than words. [Image credit, MTY.]
Palanca - [Lever] Any armbar.
Patada - Kick.
Patadas Voladoras - Dropkick (or flying dropkick). Used in a plural form (patadas) since, at least in theory, both feet connect. In Mexico many wrestlers use a dropkick falling flat on their back, and sometimes this kind of kick is called "Patadas de Canguro a la Fishman" (Fishman's Kangaroo Kick).
Pescado - Slingshot bodyblock.
Plancha - [Iron board] Any move in which the attacker connects with his chest/abdominal area, like a splash or a cross body block.
Puente Olímpico - [Olympic Bridge] Japanese leg roll clutch.
Puñetazo - Punch.
Quebrada - A moonsault after springboard off the second drop. Also called Asai Moonsault as it was popularized by Yoshihiro "Ultimo Dragon" Asai- though Asai Moonsault generally refers to the version of the move executed to the floor. The quebrada was invented by the original Fantasma de la Quebrada.
Quebradora - Generic term for backbreaker.
Quebradora con giro - Tilt-a-whirl backbreaker. "Con Giro" is often misspelled as "Con Hilo" (bad translation from Japanese).

Quebradora en todo lo alto - Torture rack.
Casadora - A luchador throws himself into a wheelbarrow position, often as setup for an armdrag or, sometimes (more commonly in the U.S.), a bulldog.
Rana - The linked pinning position. A rana is JUST the pinning position, not the actual movement done before reaching that position. The finishing position of a sunset flip is also a rana. [PICTURE]
Reinera - Back-to-back standing (and usually spinning) torture rack. Invented by Rolando Vera.
Ringuina - Ringo Mendoza's trademark submission where first he grabs his opponent's arm, steps behind him, grapevines his leg and catches him in an back hammerlock. Attacker then rolls to a side, puts his leg onto his opponent's neck and shoulder and forms a grounded octopus submission hold [thanks to Canz for the detailed explanation].
Salida de Bandera - Over the top rope bump. Also called "Jerry Bump" on the internet, since Jerry Estrada used to be the king of the salida de bandera during AAA's best days.

Tope con Giro - Literally, Tope with a twist. Often misspelled as "tope con hilo" (again, bad Japanese translation).

Tapatía - [the one from Jalisco] An inverted surfboard.
Tornillo - Any spinning or corkscrew move
Valaguesa - Attacker sets opponent on top rope, bending their body forward. He then puts his left shoulder against the back of the opponent's neck, hooks both legs and lifts him off in that position, so he ends up vertically folded on his shoulder. Finally he jumps and kneels down, bending the opponent with a lot of pressure on his neck. The jump is often done after spinning a few times. Often referred to in English as the Muscle Buster or Kinniku Buster (in reference to the "Ultimate M.U.S.C.L.E." character's finisher)
