Based on watching recent British TV shows on BBC America, "a fortnight" and "sh'y'te" are being replaced with "two weeks" and "sh'i't".

In Scotland, I saw road signs for "trucks" and not lorries; so, do "trucks" refer to what we call "18-wheelers"? A rise in the road is called a "summit". And, "Chemist shops" seem to be called "pharmacies" more and more.

Is a sedan still called a "saloon"?

In the U.S., the cockney slang of "raspberry (tart)" is referred to as a "Bronx Cheer" - (referring to New Yankee Baseball fans reaction to team results).

Over here, "knickers" referred to as "panties".
