From Fancyclopedia 2, ca. 1959

HC Konig made a hobby of collecting quotations from stories in which characters are supposed to "hiss" sentences ("Don't come near me, you brute!") in which most people couldn't find anything to hiss. He then became known as The Old Hisser himself. Later, Wollheim pointed out that Heck had been too thoro; he had collected so many examples that what he proved was not that the writers were careless, but that "hiss" had a meaning ( "to speak with whispered sinister intent") lexicographers had neglected to note.
