Joe McVeigh’s Intro to TESOL course put together a great slang dictionary last month. Slang is a bit like IT vocab - some of it gets obsolete quickly - so this is a nice example of what’s current in US universities. It also has audio examples. Follow the links off the post.

And in case you haven’t checked out Joe’s site, there are some great resources there - he’s the real deal - including some nice needs assessment stuff.
