Don’t pretend you didn’t become obsessed with whatever cool new slang was flavour of the month when you were a child
I don’t remember getting any new slang as a kid.
You were learning slang along with everything else. At that age, it doesn’t stand out against everything else the same way it does when you’re older.
I think this is true, but I also grew up without Internet or social media so maybe things were more regional as opposed to this larger shared culture those things have enabled. So that may be part of it?
