generation gap terminology

Just saw a FB posting on things kids growing up in the 90's would understand, like Nokia phones and dial-up internet connection. Then I saw a program on TV about the older generation using different terms and gestures. So on the heels of OMS's post about surfing terminology and how names for the same maneuver have changed, here's a question . How many of you younger generation know what " rolling up the windows " means in surfing terms ?
