What the heck is a »Kauboy«?

The name »Kauboy« is a word-play only understandable in the german language. The german word »Kau« sounds like the english "Cow" but it does mean to chew. So, »Kauboy« is pronounced exactly like "Cowboy" but does not have anything to do with western, but with chewing gums... Therefore the english title for the film is: "Troublegum"
