The Saugendampf (ZOW-gən-dompf; pl: -dämpfe (-daymp-fə); Ger. saugen "to suck" + Dampf "vapor") is the horn-like pipe Clint and Joshua were using to smoke Jay. The pipe has a huge end like a horn to inhale as much vapor as possible. According to Monroe, dedicated Jay addicts own and use these pipes.
Trauminsel (TROWM-in-səl; pl: -inseln; Ger. "dream island") or island of dreams is a slang term for a Jay crackhouse. There is at least one located in Portland, Oregon, though Rosalee Calvert said that they were "everywhere."
(Note: It is assumed that there are very few or no Trauminsels at all in Seattle, Washington, since Rosalee went there to get clean of smoking Jay.)
