Smoking cigars.

It is a skill that takes a long fucking time to master. Only a non-cigar smoker thinks you light it and you're good. Omg no.

Don't take up cigar smoking unless you want to waste $1,000 choking on cigars while you learn how to smoke them.

E: also pipe smoking. So profoundly satisfying, but it takes so much skill to get a good smoke that it's not even worth it. I have been smoking pipe for over 5 years and I still don't know what the fuck I'm doing although I'm getting a lot better.
