I'm glad snor doesn't have the same meaning as in Swedish. In Swedish, it means snot.
..but if the snot is really big and juicy, you can make a string from it. (voilà, it'll be easier for me to remember snor=string by this nemonic "snor is a snot turned into a string") ;-P
Oh come on. "Green string soup" is a typical Danish meal, don't feel so offended =D
That's not a string sir, that's our famous caterpillar soup - Special du jour.
If there are lots of strings in your suppe, you might be confusing it with your Von Suppé.
