Yaderhey 

A word used in Wisconsin, Michigan and surrounding areas that translates to "Yes," or, "Yes, I agree." It is similar to "ya know hey."

Yaderhey is thought to be the opposite of a phrase derived from Bob and Doug McKenzie in the movie Stange Brew, "No way, eh." You would then replay, "Yaderhey."

Bob: Hey man, that was a hot chicky last night at the ho-down, eh?

Doug: Yaderhey!
