yeah that's certainly an option, but defining a toxic personality or a toxic personality trait in it of itself is a really hard and difficult process, and doing that externally is arguably worse. As it's rife for gaslighting and abuse, but that's a different story.

As for crude jokes, if you mean like, sexual harassment i think that's different. I think crude language in general is perfectly reasonable, though the trick is obviously being able to read the room. There's a fine line between hanging with the friends, and then being a fucking asshole.
