This clip comes from the world of the Dutch kermis, the travelling fairgrounds where ride operators use loud announcements to warn visitors and build excitement before a ride starts. The Dutch phrase translates as watch out, we are starting now, which explains why it works so well outside its original setting. On soundboards and in short videos it is now used as a universal starting signal, instantly understood even by listeners who do not speak Dutch because the tone, pace and fairground atmosphere carry the meaning.
