Fair point about interesting, I will say the variety of different American slangs and vernaculars are bordering on being classed as distinct dialects which is fascinating. Not to mention niche culture terms like "based" becoming mainstream amongst the Anglosphere.

Which is one of the things, biased as I am about my native language, I like about English: it will accept any commonly spoken enough words into the dictionary.

So in that respect, I propose an exchange of terms that I think Americans might enjoy using:

"Naff" - lacking in style or good taste: vulgar and unfashionable. I think this would be great due to the distinct difference in the 'AA' vowl that would be delightful in a southern drawl. It originally came from Polari and Carnival Speak and has fallen out of fashion (ironically) but I think could see a new lease of life on your continent.

"Mithering" - To make an unnecessary fuss or moan. Since I've seen a lot of clips from Game Of Thrones around Americans liking the use of "Whinging" over "Whining" I think y'all would like an alternative to "Bothering".

"Bodge / Bodged" - to do something clumsily or quickly as a temporary measure. I think this one would be excellent as an alternative to "Jerry-rig / Jerry-rigged". Especially as an enjoyer of high-quality "Redneck-engineering" which I occasionally come across on my feeds. Because there's an art to throwing something together with what you have around you based on experience and guesswork that somehow just works beautifully right when you need it to.

Especially with America's history of large and successful inventions spawning from garages much like in the UK coming from small garden sheds all starting from barely-working prototypes.
