It's something you don't see so often here, it's alien. If you spoke to people like that they'd presume you were a psychopath, and it's extremely patronising.
I saw one of Beckham's kids on some cooking show in America and the lad made a fucking bacon, sausage and egg sandwich (lmao), and when he handed it to one of the hosts she made this similarly ridiculous exclamation like it was the best thing she had ever tasted. I thought it was a comedy skit.
