Whistling in public
Generally speaking, you won't find many Koreans whistling in public as this is construed as being rude, vulgar and of low class standing, having little to no formal education. Many Korean do know how to whistle and quite enjoy it in the privacy of their own three foot bubble when no one's really paying attention or in their homes working on a projects. Next time you happen to be in an open market, take a closer look at who's whistling and who's not. It'll usually be the scruffier looking dude working a blue collar job.
