Over in Midwest USA, it always meant, usually (but not always) adversarially, “so you can ponder THAT all night, and no matter how much you think about it, will change neither the facts nor the conclusion.” The only local color I have to add is that it was also somewhat normal to hear “put that in your peace pipe and smoke it” and also “so you can shove that in your peace pipe, and smoke it,” both being references to the custom among some Native North American nations to share a “peace pipe” as a kind of diplomatic gesture, but turned on its head. This had the effect of me always believing and perceiving it as (usually) especially sarcastic, but largely deriving from the exact meaning that it originates from, even if the cultural reasons were obfuscated.
