So... to start the movement around here, let's make this pool o/
Obs: If you don't know one of the attacks u can acces this website to know in which chapter Zoro uses it: http://www.arlongpark.net/Characters/Zoro and then check on One Manga or something ;)
Obs2: I only wrote down attacks up until the anime, in other words, up until he defeated Kaku.
A little update on the attacks!
Oni Giri (Demon Cut)
It is Zoro's most common move. He starts with a sword in each hand and one in his mouth, and he crosses his arms. He then charges and performs two horizontal slashes at the same time by uncrossing his hands. The pun of the attack is that if we read "Onigiri" (all together) the meaning is "rice ball", in memory to Rika.

Tora Gari (Tiger Hunting)
It's the technique where Zoro holds both swords on one side of his body, tips pointing down. The sword in his mouth is perpendicular to the two blades, and he slashes forward. The pun is in "Toragari" (all together) wich is a mohican haircut.

San Zen Se Kai (3000 Worlds)
Could either be translated as "3000 Worlds" or "The Entire World/Universe", this is San Tou Ryuu's succession technique. He just spins his two swords in front of him, charges and then ends up in a crouched position with one sword in front and one behind.

Tatsu Maki (Dragon Coil)
This technique makes no sense whatsoever. A sword in each hand and his arms are stretched out. Of course, there's also the sword in his mouth. Now, he just spins, creating a tornado that is able to send opponents flying and bleeding. The pun is in "Tatsumaki" (all together) that means "Tornado".

Ushi Bari (Bull Needles)
Zoro crosses his arms and holds the two swords forwards. He dashes and hits the opponent multiple times.

Shishi Sonson (Lion Song Song)
This is an Ittou Ryuu (one sword technique) Iai attack. Iaido is a very quick style of swordsmanship that consists of four parts: drawing the blade, killing the opponent, flicking the blood off the sword and returning the sword to its scabbard.

Hyakuhachi Pondo Hou (108 Pound Cannon)
The same technique as the Sanjuuroku Pondo Hou but this time made with three swords, tripling its power

Hyou Kin Dama (Panther Kin Ball)
Zoro crouches down on all fours like a panther, then pounces at his opponent while spinning in midair. "Kin" or "koto" is a traditional stringed musical instrument from Japan played using only three fingers similar to how Zoro uses three swords and Zoro's swords strike the opponent in a similar manner as the fingers of the koto player would pluck the strings. Also "hyoukindama" all together is to call someone stupid.

Ashura Ichibugin (Asura One Fog Silver)
After using his Kiki Kyuutouryuu: Ashura move, Zoro charges at his opponent reducing all enemy attack to "mist" while he attacks him as well. This technique is very reminiscent of a move used by Kenshin Himura from the Rurouni Kenshin series called the Kuzu Ryuusen (Nine-Headed Dragon). The pun here is in "Ichibu-gin" a silver coin from the Edo period.

Gazami Dori (Crab Grab)
Zoro poses himself above his opponent's neck with swords above and beneath, and brings the swords together in a vicious attack that would usually cut off a man's head.

Ichi Gorira, Ni Gorira (One Gorilla, Two Gorilla)
A power-up technique, Zoro tenses his arms, thus causing them to become more muscular. This technique is used to prepare for his Santouryuu: Nigorizake attack.

Kiki Kyuutouryuu: Ashura (Demon Spirit Nine-Sword Style: Asura)
Zoro's strong spirit turns him into a three faces and nine arms demond. An Asura is a demigod/demon that appears in both Hindu and Buddhist mythologies with the same appearance that Zoro gained.

Sanjuuroku Pondo Hou (36 Pound Cannon)
The kanji can be read as "Thirty-Six Earthly Desires (Male) Phoenix". A one-sword technique where Zoro... fires his energy at the opponent.
