Bullshit! "Nanopiscacide!" is what the inhabitants of the planet Threlmkon say when another Threlmkonian sneezes. Well, it's not exactly sneezing as we know it, being that Threlmkonians have no mouths, noses, or respiratory tracts in general. It's more of a rapid and surprising lurch in the space-time continuum. But "Nanopiscacide!" is definitely what they say, though they don't actually say it since, as previously explained, they lack the organs necessary to say anything. They sort of mentally burp it out into a shared communal consciousness. Since said consciousness is communal, there are apt to be billions of Threlmkonians saying "Nanopiscacide!" at any given moment, which pretty much drowns out anything else being said, thus effectively making "Nanopiscacide!" the only word in the Threlmkonian vocabulary. This is good news for humans since Threlmkonians are very unfriendly and, if they didn't spend all their time saying "Nanopiscacide!", they would probably invade Earth and destroy it using some sort of super weapon which, fortunately, they haven't had time to invent since they spend all their time saying "Nanopiscacide!"
