An idiom is not a malapropism. scarface74 did not commit a malapropism, and it was hardly a case where "the person committing the error doesn't know what they did wrong." It was simply the use of a common idiom. The author knew exactly what they were saying, and everyone reading the comment understood its meaning, yourself included. A malapropism is like the Yogi Berra example in Wikipedia: "Texas has a lot of electrical votes." Few people make that particular mistake, and that's what made it funny. Of course, Yogi Berra got a lot of attention for phrases like that. So you have to wonder if he really made a dumb mistake, or if he was being dumb like a fox. But he couldn't be dumb like a fox, could he? No one thinks foxes are dumb, those sly little rascals! And that's what makes "dumb like a fox" a colorful and insightful idiom - just like "I could care less" or "I've been in your shoes." Obviously none of these is to be taken literally, and everyone knows that. Language is much more fun when we allow ourselves to play with it, rather than insist that every word be taken at its most literal meaning.
