Rosebud
from Fancyclopedia 2 ca. 1959
(Welles:Tucker) Originally the name of a boy's sled, and Citizen Kane's last word. It got into fandom when a character in Doc Lowndes' interminable fanfiction serial, Trigger Talk at Green Guna, murmured that just before kicking the bucket. The cry was repeated to Liebscher by Tucker under circumstances which gave it a special (and very kteic) fannish meaning.
