This week's words are delicious American treats to my French ears. It's like eating Jell'O! About flummadiddle: I remember from watching old movies that people (wasn't it Scarlett o'Hara?) sometimes said "diddle-ee-do", or something like that, to interrupt another speaker and reject the speech as nonsense. Could that account for the second part of the word?

As for today's word hornswoggle, horns are usually associated to cuckolds in several countries of good old Europe.
