I don't know what you would call these misused words but they're pretty funny and increasingly common:
On a personal blog:
"I didn't want him to think I took him for granite..."
(Or concrete or heaven forbid, even brick...)
In a THIS Magazine story:
"And it's healthy - hemp seed is a high source of protein and contains essential fatty assets."
(Fatty assets? Is that what happens when saddle-bags meets money bag?)
In a conversation yesterday...repeatedly used by everyone at the table except me:
"If money were no option...""If I could go anywhere and money were no option I would go to Tuscany."
(Really? If money were no object I would send you back to high school English.)
And the one I hear literally everyday at work:
"The idea just needs to be flushed out..." "Good point Caroline, can you flush it out for us a little bit?"
(I can flesh it out if you would prefer. Or hey, even better, I could get another job.)
