Experience can and often does inform inspiration.  For instance, last night I sneezed so hard that I farted at the same time and I immediately coined these interrelated functions a "fartchoo" .  Yes, a fartchoo.  Feel free to use the word whenever you accomplish the deed.  Today, I Googled "fartchoo" and only found one suggestive but not clearly explanatory instance of it used as an exclamation on a Chinese web site.  Such a use, in my estimation, does not constitute declaring a new word and demonstrating its utility with a precise meaning.  Right?  So next time you fart and sneeze at the same time, shout "fartchoo" (instead of "achoo").  And think of me.
