"icebox" When I was a kid, older folks were still calling electric refrigerators
I always register slight amusement when you hear that phrase which was relatively common thru 1970s TVshows with older characters. At least it makes sense as a description. Whereas "hold the wire" (which I heard last night) meaning "don't hang up the phone" is opaque. Maybe it was an abbreviation for "hold the wire circuit open."
"Drop a dime" - Which meant to use a payphone to call the police on someone. "I'm gonna drop a dime on you, pal!". Do payphones still exist? Related - "Long distance" phone call. "A call for you, honey. It's long distance!"
