Çüş

'Çüş' (pronounced 'tschüsch') comes from Turkish, where it was originally an agricultural call to donkeys or horses to make them stop (similar to English 'whoa'/'brr'). It entered German youth slang chiefly through the track 'Çüş Junge' by Fler and Muhabbet (2006). Today it expresses astonishment or emphasis - like 'whoa', 'krass' or 'man' - but depending on context can also be dismissive, like 'yuck'.
