This article from the Guardian made me smile.

I’m sure that we all have favourite silly words. Diphthong sounds a lot ruder than it is, while dongle is always good for a smirk – such as when innocently saying things such as “I recharged my dongle” or “I dropped my dongle down the back of the sofa.”
Scrumping is something that I did a lot of as a child, as there was an abandoned orchard nearby, and the word is pleasingly silly and naughty, inviting emphasis when said—and I wouldn’t feel a wazzock for doing so.
I like the word copacetic, which I came across in James Lee Burke’s novels, before living in Atlanta, Georgia for three years. I was delighted to hear people using it there. It’s definitely an Americanism, and I like throwing it into conversations as most Brits wonder what the hell I’m saying!
