Oh there are too many!
But the one that really makes me want to punch the perpetrator repeatedly in the face is "lush".
"This meal is lush"
No it is not lush. It is good, satisfactory, nice, amazing, tasty. Any adjective you can think of. But it is NOT lush.
Im not sure if this is a thing outside the UK as ive never noticed it abroad.
Like with many of our modern social stereotypes in this country, I blame The Only Way is Essex.
One can easily see that "lush", in the sense of a tasty meal, could be derived from "luscious" (having a delicious taste or smell).
But, to my surprise, my Webster's 9th Collegiate Dictionary also lists "lush" with definitions:
2a. Savory, Delicious
2b. Appealing to the senses.
Now, if you DRINK your meal, that can open another can of worms.
Facts are fragile things. Treat them with care. Sources are important. Alternative facts do not exist.
