The one that gets me the most is English people suddenly saying "fall" instead of "autumn".

It is a traditional one which fell out of fashion.

Now if we start saying "diaper" again instead of "nappy", you can start to worry.

The weirdest one to me is the English suddenly referring to police as "feds".

It's not like they didn't already have dozens of slang terms for the police.
