Youth-Speak

It seems like only yesterday I was enjoying youthful slang the older generation couldn't comprehend: phoning my 'rents, drinking pints of 'ken in student bars. Omg I used a lot of TLAs and had a rising intonation? Now I am on the outside and I have no idea whether the kids are alright because I don't understand a word:

A student I trained with at kung fu asked me what I did for a living. When I told him I was a software developer he said, "Aw, man, savage!". I don't even know whether that's good or bad!

Squealed by a youngster working in our sales dept, "Oooo, cool beans!". Makes me think of cold baked beans. Ugh...

From a conversation I overheard between two girls dressed like something out of Desperately Seeking Susan, "So, he's like, 'What's her complexion like?' And I'm like, 'Mmmm 'spretty vaz.'". WTF? Did I even hear that right?
