First used in the movie "Cannibal: the Musical," "Shpadoinkle" was left without a specific
definition, it's just a generic exclamation, and makes a great substitution word.
These are from the movie itself:
"Aaaah!Ohhh shpadoinkle!" - exclamation of
surprise at being caught in a
bear trap.
"Have a shpadoinkle
day." - greeting.
"She sure is a shpadoinkle horse." - compliment
