I know that "Get with It" is an idiom, but couldn't find it on this website. What does it mean? Thanks.
Didn't find it over there too...
Get with it: to become knowledgeable about the current or latest trends, fashions, or ideas, as in She just turned 60, but she's still very much with it, or Get with it, Dad, that kind of razor hasn't been made for years. [Slang; 1920s]
