Shiak

"Shiak is "stabbing". Jedi tradition holds that shiak is an honorable method of inflicting serious injury because it causes the least visible injury to the opponent's body."

- Cin Drallig

In lightsaber combat, shiak was the act of stabbing an opponent and was considered relatively honorable by the Jedi. Jedi usually stabbed in the leg or arm, however Sith preferred stabbing opponents through the chest, often guaranteeing certain death to the unfortunate victim.
