True-love has taken to doing German crosswords. Can anyone help with the meaning of this word.
Here's the background:

the word is "kuer", that is, k, u-umlaut, r. i think it may have something to do with improvised gymnastics. i've consulted all 4 of my german-english dictionaries, and googled in german, but the translations i get just render it as "kuer". is it an acronym, or somebody's name? many thanks, hildebrand
