Definitions for "Ralf"
a particularly outrageous or ludicrous puzzle used in a special section of each year's April issue of The Enigma. Ralfs (or Ralves) are purported to be written by one Ralf P. Olio as an April fool, but like Santa Claus, Ralf P. Olio has many Earthly helpers. Ralfs are known for their off-the-wall bases and for ignoring, twisting, and blatantly flouting Guide rules. The derivatives Ralfish and Ralfy are sometimes applied to non-Ralf flats. (For the transposally challenged: "Ralf P. Olio" is an anagram of "April Fool.")
