Eh. This isn't the sort of thing you should read out of a book. You should actually consume a lot of English media so that you can understand pop culture references instead of trying to memorize them from a fake dictionary. However, if you insist, I'd go with Chuck Klosterman's "Sex, Drugs, and Cocoa Puffs: A Low Culture Manifesto" and "Eating the Dinosaur". http://www.amazon.com/Sex-Drugs-Cocoa-Puffs-Manifesto/dp/0743236017 http://www.amazon.com/Eating-Dinosaur-Chuck-Klosterman/dp/B005Q5ONEI They're essay collections on some of the more important cultural waves in America, which should provide you with knowledge of the included subjects as well as major criticism and analysis of them as they pertain to American popular culture as a whole (which, for better or worse, has an incredibly strong effect on international pop culture). I don't want to recommend any Canadian, British, or Australian pop culture books due to my lack of perspective on them, of course.

I might also suggest watching daily shows which discuss topics and issues, which will help you to consume knowledge about both news and pop culture like a native. When they make a reference to something, look it up. If they don't name anything specific but you can tell they're making a reference that you don't understand, ask a native to help you. ;) My favorite shows are The Daily Show, The Colbert Report (both political satires on Comedy Central which are full of pop culture references) and The Philip DeFranco Show (on YouTube). I hope the resource you found plus these suggestions help you in your pursuit. :)

If you just want to learn about pop culture and absorb some of the language associated with American pop culture, read gossip and lifestyle magazines like People or US Magazine. They all are online and you can read English they way it's really spoken.

I found something on Amazon. http://www.amazon.com/From-Abba-Zoom-Encyclopedia-ebook/dp/B005CW0Q2I/ref=sr_1_2?s=digital-text&ie=UTF8&qid=1362759650&sr=1-2&keywords=Pop+Culture+references
