Two cohorts, the inhalant and the flatulator, arrange themselves thusly:

+ The flatulator lies, belly down, with his butt cheeks spread.

+ The inhalant sprinkles a finely-fluffed dusting of cocaine around the flatulator's anus.

+ The inhalant gets his face really, really close to the butt hole.

At this point, the flatulator earns his namesake, causing a gas expulsion from his rectum. This gaseous outburst, much like a volcano, projects dust into the air. It is then the inhalants goal to breathe in as much cocaine-fart as possible.
Hello friends, you seem like the kind of people who like to fart and do cocaine! Can I interest you in taking a Peruvian Volcano?
