The medical term for a fart is "flatulence," which is defined as "flatus expelled through the anus." Flatus is strictly defined as gas produced during digestion—generally in the tummy and/or gut. Through this book Dani and Nick are taking part in flatology, or the report of flatulence, even though their main area of expertise is not in this field.

The give-and-take "fart" dates back to the fourteenth century, earlier the term flatulence came into use, and was used specifically to hateful breaking current of air loudly. Today the term fart is more commonly used to describe any gas expelled from the terminate of an animate being that is reverse to its oral cavity—whether this be through the anus, cloaca or a specialized duct—and if information technology is audible or not. This, therefore, is the definition used throughout this volume. So, although some of the farts in this volume may not fit the strict medical definition of flatulence, they would generally be accepted as a fart to any human encountering them.
