What does a stink bug smell like?

Okay, if you want to know what a stink bug smells like you came to the right guy. My house has them and they pop out once in a while. A few hours ago, I found one swimming in my toilet! I had two options here. I could get a paper towel, pick it up from the toilet and throw it outside OR I could just pee on him right then and there. I picked the second option; worst option I ever made. The moment I started peeing on him the smell was unbearable. I was about to puke if I hadn't used my shirt as a filter. Anyways, they smell like wood/rocks/burnt tires/dust/oil. That's the best way I can describe it. Hope I helped.
