I had a brief encounter with a German couple once, and they gave me a German safe word, so they could both understand it. The word was:Donaudampfschiffahrtsgesellschaftskapitän....which means Danube steamship company captain. Germans apparently make words by stringing nouns together....such as Flugzeugabwehrkanone (FLAK) which means aircraft (Flugzeug) defense (abwehr) cannon (kanone). Anyway, they made me practice saying
"Donaudampfschiffahrtsgesellschaftskapitän" over and over then slapped a bondage gag on me and went to town. So "safe words" don't always work so well. But Germans sure do...I couldn't sit down for a week!
