ROLLER-COASTER, 1. a case that betters and worsens. A roller-coaster is always connected to a suppressive person and will not get steady gains until the suppressive is found on the case or the basic suppressive person earlier. Because the case doesn’t get well he or she is a potential trouble source to us, to others and to himself. (HCOB 8 Nov 65) 2. a slump after a gain. Pcs who do not hold their gains are PTS. (HCOB 9 Dec 71RA) 3. gets better, gets worse, gets better, gets worse. (SH Spec 63, 6506C08 )
ROLLER-COASTERING, the PTS is known by roller-coastering (Coney Island fast up and down quarter-mile of aerial railway). They slump. (HCOB 3 Apr 66)
ROLLYCOASTER CASE, Slang. a potential trouble source, and just on the other side of him there is a suppressive person invalidating his gains. He’s never going to get any better, not until he is labeled a potential trouble source and told to handle. (SH Spec 61, 6505C18)
