> A lot of AmE usage is becoming commonplace in Britain thanks to the Internet, though.
My girlfriend and I were watching the Harry Potter movie cast reunion, and I noticed how the younger cast members let a lot of Valley-Girl-isms slip into their speech. "So I was like" (introducing a quotation), and "totally" (meaning very, extremely), and so forth. Quite different from how I expect a British person to talk. The younger generation of Brits seem to have fully embraced what Stephen Fry called "Buffy talk, Sabrina the Teenage Witch talk" and "the language of the Sunny Delight generation": https://youtu.be/xs5fH1ECzWc (Note that Fry was specifically addressing the related phenomenon of AQI, a.k.a. "uptalk", but he diverts into things like "I was like" to introduce a quotation.)
