"Schnozzle" refers to the word "nose", first utilized by Randall Patrick McMurphy, in 3566 B.C. in the latin form, Nozillius, later integrated into the hit british rock sensation, the farfignugens, as Nonozze. Most recently adapted by the late KC Baldwin, circa 2005, as the word we all know, use, and love, Schnozzle.

A Schnozzle is when you sneeze and a large amount of snot (also known as bogies or nasal mucus) is produced from this sneeze, either into a tissue or into your own hands. This is not regarded as classy in the upper class world.
