"Brain rot" is just the new term for "slang that old people don't understand".
"Cool" and "for real" are no different than "rizz" and "no cap". You spoke "brain rot" once, and "cringed" when your parents didn't understand. The cycle repeats.

Brain rot in this context is not a reference to slang.
I suppose I should have replied to one of the many comments here where my response is the correct context, rather than a top level.
