Shol'va is the Goa'uld word for traitor. It refers to a Jaffa who has betrayed the Goa'uld to whom he was in service to. The word also has heretical connotations, as the Goa'uld serve as the Jaffa's gods. Oftentimes, "shol'va" was the name used by both the Goa'uld and the Jaffa to address Teal'c after he betrayed Apophis. (SG1: "The Nox", "Bloodlines")
