Reddit mentions of Che Boludo: A Gringo's Guide to Understanding the Argentines

Here is the Amazon link to Che boludo and here's the link to Speaking argento

About books IN español argentino, I'm reading Papeles en el viento from Sacheri (the same guy who wrote the book in which El secreto de sus ojos is based. By the way, you should see that movie). Chapters are short and easy to read, and it's pure español argentino, with all of our attitudes and cursing :P

You need to learn some Spanish, then you can read this book to help you with our slang Che Boludo: A Gringo's Guide To Understanding The Argentines ($57 for a used book???).

Here is the scanned PDF.

OP, this little book might help you.

This will come in handy.

Edit: saved you a few bucks.
