As a native speaker in Chicagoland, I've never heard this. Where is this sort of idiom common? I heard it originally from someone who might be Brit. Is this used in other parts of the US? Across the pond? Down under or among Kiwis? Canucks? Is it used in the Midwest and I just haven't heard it? Anyone know of any resources that would confirm that this is common US vernacular and not just a dialect some dictionary writer decided to include out of his fondness of the King's English?
I'm looking for evidence or citations that characterizes the sorts of language communities that use this English idiom, and am not seeking to conduct a survey, as per Stuart F's objection (though given my lack of explicit caveatation, I can see why he might object). Please, whatever you do, don't characterize your personal English Language and Usage.
