Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
Well, I'm not sure if it's "misworded" or just one of several variations of the phrase. Other slight variations I've heard are "close to the vest" "keeping your cards close to your chest," "playing your cards close to the vest/chest," but they all mean the same thing of course, just that someone isn't being completely open about what they are doing. Try Googling it without quotes around it and you'll find a ton more.
It may be a mismatch, or Nolan may have done it on purpose to keep making slight references to playing cards with the whole Joker thing, but I doubt it. It's really not my place to say.
