That's wild!
In 1987 I acquired a division of Paph. Pisar 'Innerarity', AM/AOS and when I showed it off, heard almost word for word that exact explanation from Dan Harvey. He didn't say who it was, but told me that "the guy" who named it was so mad about the shape being wimpy and the color all washed out that he chose the epithet "Pisar" with the intent that it be mispronounced as the colorful pejorative term with a slightly different spelling.
At the time I thought Dan was pulling my leg at the time, but apparently not!
