"Sithspit" served as a phrase to communicate frustration or resentment towards an object or individual. In 34 ABY, the smelter droid 8D-J8 voiced his discontent, branding them as "sithspit" upon observing a First Order shuttle above his establishment, further stating that the First Order's presence would lead to his financial ruin. The expression could also convey disbelief, exemplified by Gora's statement, "What a load of Sith spit". The term sithspitting functioned as a disparaging descriptive word.
The initial appearance of "Sithspit" occurred in Galaxy's Edge 1, a comic authored by Ethan Sacks and visually rendered by Will Sliney. Its release date was April 24, 2019. Furthermore, "Sithspit" is referenced frequently within Star Wars Legends, including instances in Side Trip, Luke Skywalker and the Shadows of Mindor, and numerous other works.
