Confidence
(historical origin)

Confi was never good at anything. He was too stiff and had no flexibility at all. He had to sleep standing up.
But he had his dreams like we all have one time or another, and one fine day he started to swagger about humming a popular tune of the day.
People came up to him and asked him what he was doing,.
Confi answered: "I'm dancing" and the people said: "No you are not! You're swagging!"
"No" Confi said: "I am dancing"

And there you have It!
In the older times people said Confi dancing when they were talking about someone who believed in themselves and what they were doing.
With time the words joined and then someone inflicted a spelling mistake ....

Come back next week for another word!
