They said groovy in the sixties...what did they say in the fifties, seventies, eighties, and nineties?

I think in the '50's, they said "ginchy" and "cool"( I got that from "Happy Days"...); in the '70's, they said "dynamite" and "right on"; in the '80's, they said "awesome", and "bitchin'", and the '90's I've no clue...
