I am a big giant athiest and I always wondered why whenever I sneezed somebody tried to bless me. First of all I don't want to be blessed, and second, I don't think that these people who kept saying it had the power to bless me even if I wanted them to. Something had to be done. I wasn't happy with all of the foreign variations. Salud and gesundheit are from a different language, I wanted something non-denominational in English.

So I invented the word Snarfle - (snär-fuh l) Function: adjective
adj: To publicly acknowledge and express that someone has sneezed.

I began using it a few months ago consistently to anyone who has sneezed. And since then a handful of my friends now use it exclusively to mark the passage of a sneeze. My niece now uses the term as well. But most importantly I sometimes work with Mexicans who don't speak English and are always asking me how to say things in English, for example they might say "¿Como se dice arbol?" And I would reply "Tree". Well one day I was asked how to say salud in English and I told them it was snarfle. So now there are three Mexicans who believe the actual English word is snarfle. And they will go forth and propagate this new word.

(I have also implanted the new word "rocktastic" into common vernacular, but I'm not sure if I invented it, or rather, I'm not sure that I'm the first to invent that word, so I leave that one off)

Feel free to use "snarfle" to acknowledge when somebody sneezes henceforth.
