I love malapropisms (using the wrong words to obfuscate meaning), such as dancing the flamingo, or teaching family values as the bondage between mother and child.
Word abuse like that is now called a Bushism, named after a grating great man who was ungratefully “misterunderestimated.”
But I’m not really well versed enough to understand the nuances of advanced wordplay, juggling between mondegreens, eggcorns, spoonerisms and other side dishes of word salad. I usually wade in the kiddie pool of language and limit myself to idioms.
Idioms can be truly bizarre when you take the time to think about them. Like saying that something costs an arm and a leg. So what can you get for a spleen and a gall bladder?
Now, one of the most overused colloquialisms is “Practice what you preach.” Some people liken this to meaning “Walk the walk and talk the talk.”
Actually, the correct terminology should be “Walk the talk,” meaning to follow a set of rules or directions that you expect others to follow.
All too often however, the intended meaning is, “Do as I say, not as I do.”
A perfect case in point would be Bristol Palin, who was paid by the Candie’s Foundation to promote “her message” on the importance of abstinence.
