What people here in New Jersey call going to the beach. What some people don't get, however, is that this is more the term used to discribe the trip taken while going "down the shore" from your home in an inland county or town. The drive to whichever beach town you are going to be spending time in is going down the shore, but once you're there you simply go to the beach.
In the song "New York City Girl", the singer tells the New York City Girl that "you should know the score by now". Meaning she shouldn't be so naive. She shouldn't think that love is going to be like the Broadway shows, i.e fairy tale like. She's had enough bad experiences to know better, "to know the score by now"!
