"Sithspit" was one of the most common curse words used throughout the era of the Galactic Republic, through the Galactic Empire, and into the time of the Galactic Alliance. Originating on Corellia, it expressed outrage, surprise, pain, frustration, or simply displeasure. Although it was a nonsense word, the inclusion of 'Sith' was probably a jab toward the age-old enemies of the Republic and the Jedi.
