That's a lot of years there. And a lot of years equals a lot of words. I'm gonna give you a few interesting ones and then I'm gonna give you a few links so you can find more yourself. It's always better to teach someone to fish than to give him or her a fish [if one can learn to fish ones self one can fish forever while a single fish is gone in a flash]. Here:
bad news: depressing person
bake biscuits: to make records
flutter bum: a good-looking boy
hipster: same as above (hip) <-- this actually dates from before the 50s
ice it: tell someone to forget something
like crazy; like wow: really good, better than cool
panic and a half: a very funny joke
go ape: go nuts
bitchen: awesome
cat: guy, dude
jonesin: needing something obsessively
keep on truckin: hang in there
hang in there: keep on keeping on
keep on keeping on: stay okay, keep going even when the world's got you down
Anyway. The 50s site listed below is the best. The 60s and 70s have some errors but some interest as well. Anything newer I think you can find. Good luck.
