Oh, but there is so much. Asking this question is like asking about the slang from now and expecting to get a four word answer. And even in the 50s, even without the internet or cable or, really, anything that would provide mass transmission of, really, much of anything other than via the simplest airwaves--still, still language changed as it does now, at a rapid rate.

Among which, under only the letter T, I found:

Total - To completely destroy, most often in reference to a car
and, of course, there is far more under the other letters. Not only that, but there are more slang sites to explore if you only, you know, do it.
