My husband is Dutch and I Iived in Holland for about ten years. It made me laugh when I learnt the Dutch word for mucous: SLIJM (pronounced "slame") of course it made me think of SLIME. Very descriptive LOL
Then in German it's pretty funny too, SCHLEIM.
Off topic for a lung forum, but the German word for diarrhoea is hilarious too: DURCHFALL literally translated as THROUGH FALL .
I'm a bit of a language nerd so I find these things very entertaining, I hope they gave you a laugh too.
