I've noticed that "Santa" is really starting to displace "Father Christmas" in British English. When I was a kid if you said "Santa" you'd have been scolded for using the American name, but listening to kids now I hear them say "Santa" all the time. I blame TV.
"Crosswalk" sounds extremely American to me and I've never heard anyone say it in Britain, but maybe I'm just getting old.
