Are other traits as well-known as intro/extraversion?

Well, looking at the Big Five personality traits https://en.wikipedia.org/wiki/Big_Five_personality_traits

Neuroticism has been in the common parlance for at least as long as I've been alive. I remember seeing sitcoms in the 90s that used the term casually and without explaining what it meant.

In this category I think you could also include things like narcissism or megalomania. Moving from psychological traits to the realm of mental illness, people have been using "OCD" as a sort of intensified form of "extremely neat" for at least a decade and a half. And of course "autism", which is used casually and pejoratively on the internet all the time. And in a non-pejorative context it's not uncommon to hear people say that such and such a person has "aspie" tendencies.
