What's the difference between i.e. and e.g.?
To play a supporting or minor role in relation to someone else: “Tired of playing second fiddle, she resigned and started her own company.” In an orchestra, the position of second violinist (fiddle) is not as glamorous as that of first violinist.
To be in an inferior position; lack power or will to lead: They won't play second fiddle to their spouses anymore (1809+)
