I would like to apologise to all Danes for spilling the beans on this but

Jeans are referred to as "cowboybukser" (cowboy pants) in Danish

By extension, all denim clothes are cowboy-whatever in Danish

As a result of this, my partner's washing machine has a setting that's only labelled "Cowboy"

@anarchiv I remember once in the 1980s, a criminal (bank robber or something) escaped with the boat from Copenhagen to Malmö. The Swedish cops looked for him on arrival, but did not get him, because the Danish cops had described him as dressed in “cowboytøj”, so the Swedes looked for someone dressed up as a cowboy.
@avadeaux This made me laugh out loud, thanks for sharing
