- a person is an R/Ser where R/Ses have to do with Scn or one or more areas of the old Scn List One found in the Book of E-meter Drills. (HCOB 1 Nov 74)
- a person who rock slams on Scn or auditors or the like. (HCOB 17 Oct 62)
- it isn't somebody you can get a rock slam on, you would be wrong if you assumed that. It means it's somebody who gets a rock slam when you ask them: "Consider overts against Scn" and that broadens out of course against Ron, against the organization or against an auditor. (SH Spec 198, 6210C04)
