Ferschlugginer
from Fancyclopedia 2 ca. 1959
A Mad-word; "a sort of clean dirty word". From Yiddish "far-schlogner", which we may translate "all beat up".

from Fancyclopedia 2 Supplement ca. 1960:
Alternatively Furschlugginer. A second possible derivation would consider it a portmanteau-wor from Ferschimmelt (moldy) and meschugginer (insane).
