When you have teenagers, your cultural consciousness will be reset to the much, much faster flow of that age. And you will return to the era of non-stop slang and hipness.
Stan-ing is very much a common term for Gen-z. And they have stan accounts. And I sort of get it. :)
This happens gradually, but started in full force at my house around age 15.
I have 3 boys, 13-18. It's an incredible amount of fun.
