Gizmo Caca

The pilots of the Royal Air Force are attributed to the origin of the word X. The earliest recorded use of the word X, in print occurs in the RAF journal "Aeroplane" (1929), in Malta:

When you're seven miles up in the heavens,
And it's fifty degrees below zero
....................
When you're thousands of miles from nowhere
And there's nothing below but the drink
It's then you will see the X
Green and gamboge and gold
Male and female and neuter
X both young and old
...................

Some people attribute the origin of this word to the Old English term ______ (to vex) or the Irish-Gaelic word _____ (ill-humoured ______).

This word was an indigenous slang to the Royal Air Force, until author Roald Dahl popularized the idea in his novel "The X" (1943). Roald Dahl was so interested by the idea, that he gave specific names to the genders: widgets (male) & fifinellas (female), and sent a finshed manuscript to Walt Disney.

X also has its own share of TV apperances; in: Merrie Melodies (with Bugs Bunny), Nightmare at 20,000 feet, The Simpsons (Terror at 5 1/2 feet) etc. All subsequent appearances paralleled X's role in Nightmare at 20,000 feet.
