What does dit klop net nie mean in English?

Answer 1

It is probably a dialect, problably from Drenthe, Groningen or a Frisian dialect.

They are different from regular Dutch and can mean different things.

For example: "'t ken ne(t)" means that "it can barely" (be done) in Dutch, while it means that "it can't" (be done) in Frysian dialect.

But to get back to your question: it means that "this doesn't make sense" or "this is not right/doesn't add up" or "this is incorrect".
