The Forbidden Forms were forms of lightsaber combat used by the Sith during the Sith Wars. According to the testimonies of the Jedi Cervil the Uncanny,
Form VII: Juyo (or Vaapad)
Form VII is the last known form of lightsaber combat and is known to be the most aggressive. Jedi Master Mace windu is the main Jedi known to use this form of combat because Form VII is the most aggressive and only the most Force-sensitive individuals can execute this form successfully.
The Forbidden was a modified Lambda-class T-4a shuttle, which was assigned to Rogue Squadron in 6 ABY. It had been modified by the New Republic for training purposes. It was intended to simulate an Alpha-class Xg-1 Star Wing assault gunboat, and was equipped with a targeting system for concussion missiles.
Order 67 was an order requiring clone troopers to begin dancing. During the Battle of Utapau, Darth Sidious accidentally executed Order 67 when he meant to use Order 66. Just after the order was executed, Cody and his troops began dancing.

Darth Vader, a master of Form V since his early days as a Jedi Knight, became much stronger after he became a cyborg. After turning to the dark side in 19 BBY, Anakin Skywalker, now known as Darth Vader, dueled and was nearly killed by his former Jedi Master, Obi-Wan Kenobi, on the planet Mustafar.
Classical Juyo
Juyo was described as the most vicious form of lightsaber combat and was said to be filled with both fury and "malignant grace." The form was given the title of the most difficult and demanding form in all of the lightsaber combat.
Lightsabers with ghostfire crystal cores also generated almost no sound and produced illusory afterimages of the blade that followed the motions of the wielder, the most curious effect of all which disguised the true position of the blade while also disorienting foes.
Shadday Potkin duels Darth Vader using a cortosis blade. Cortosis ore was a very rare, brittle, fibrous material, the conductive properties of which would cause lightsabers to temporarily short out upon contact.
Few Materials Can Repel Star Wars' Lightsabers
The most recognizable lightsaber-resistant material would be beskar, the silver metal featured throughout The Mandalorian. Beskar could only be found on the planet Mandalore and its moon Concordia, and only became rarer after the Empire destroyed much of the system.
Notable practitioners
In more recent years, the form was mastered by the Jedi swordmaster Cin Drallig along with the other six forms. Grand Master Yoda and Swordmaster Mace Windu were also proficient in its usage, as they were said to have fully mastered all the seven forms of lightsaber combat.
An example of a Jedi swordmaster was Mace Windu, considered as such because he was a master of all forms of lightsaber combat and due to his mastery of Vaapad, which he created.
Sokan was a form of lightsaber combat. Developed by the ancient Jedi Knights during the Great Sith War, Sokan combined tactics that allowed for evasion and mobility with the kinetic motions of Form V combat.

Kriff was a vulgar expletive. Kriffing was a derogatory modifier based on the word kriff.
More common Star Wars swear words and curse phrases include the likes of "kriffing," "karabast," and "e chu ta." The old Expanded Universe introduced a range of profanities inspired by the Sith, who serve as the Devil figures in many galactic mythologies; there were even some amusing ones inspired by Palpatine himself.
