Trailer park boys regularly address the film crew. In one of the later seasons Tom Arnold plays himself as a superfan of the show, and geeks out over the characters
You say "off of". In the UK we just say off. "Get off my lawn" Vs "Get off of my lawn". Why do you need the extra word?

On that note, trespassing seems much more serious in America. In a lot of the world you can just wander around, if it's on somebody else's land it's no big deal as long as you don't cause a mess.
For the culture thing, Americans are generally louder and less subtle than any other nationality. They're more friendly and energetic. There's a certain type of dry sarcastic humour that never lands with Americans. I don't want to call it British humour because there's never any confusion with the rest of Europe
I think there are too many communities. People tried to replicate reddit's diversity and places got spread too thin. When Reddit first started it didn't even have subreddits.
I've noticed the same goes for movies. There's plenty of funny films with comedy as the second genre, but never as the purpose of the film. Think of Superbad, Dumb & Dumber, Police Academy. The main purpose was to laugh! But now it's always romcoms, dramedies, or wise cracking superheroes.
