Malapropisms

So, they're not really malapropisms, but you know when students don't get an idiom quite right? But somehow, it makes sense? I'm not talking about the student who spelled segue "segway," and misunderstood my oral correction, so that it showed up in the next draft as "segueway." No, these are the ones that really kinda work. Maybe these are the idioms of tomorrow.

So, today's: in a description of the big Buffalo snowstorm of October 2006, as branches cascaded down on his mother's flower beds, all "were destroyed in one foul swoop."

No, doesn't that just make sense?
