If history has taught us anything, it's that any feature linguistically endemic to the northern half of Great Britain is dying. (Actually, I have no idea... But, y'know. Media bleaching.) I'd wager that any evidence of such features occurring across the pond is either coincidental or vestigial.

Additionally: shame on you for assuming the linguistic playfulness popular in online conversation, especially headlines, constitutes conversational English. If it's not being used regularly and casually within the content of a post, it would be best to simply assume you are observing a self-aware fad.
