Dear Americans. A legit British English word which entered English from French in the 15th century, is "trumpery".
Meaning something that looks flashy or attractive but is actually cheap, fake or without value. Applied to speech it's almost synonymous with the USian "trash talk".
Also, long before Donnie came along, in British slang to trump meant to fart.
I would love for y'all to co-opt these words because there is plausible deniability: they're already in the dictionaries!
You're welcome.
