Is the word "diabolical" actually used in real life conversations?

I have noticed an increased usage of this word, or at least I'm seeing it being used more often on Reddit. Occasionally I'll see it on Instagram in the comments. I don't use tiktok or YouTube as much.

Thing is, I never ever hear anyone say or use the word "diabolical" in any real life conversation anywhere at all. I've lived and worked in 6 states in different time zones, and have visited over 7 more so I think exposure to other people isn't a limiting factor here.

Do people really use this word in real life or is it just internet speak? For people who really do use it in real life conversations, who are you and how did it get into your vocabulary? I'm curious 🧐
