Oh wee! Oh wee!(pronounced: oh way!) is an interjection in every day Dutch spoken and written language. Could it not have come directly from Latin to German and Dutch and from there to Yiddish?

'Oh wee!Oh wee!' means: 'watch out! Here comes the bogerman!------
'Oh wee!Oh wee!'- He broke his leg!'
'Oh wee!Oh wee!'- The house is on fire!'
Any horror, pain or disaster.
