> You're like sardines, very many but only enough for one wrapped piece of fish.
Fish are properly wrapped individually in a leaf for cooking, but sardines are so small that a bunch of them may be wrapped together to make up only one small bundle. The idiom may be applied to a numerous but weak enemy or to a clan that is large but ineffective as in raising money for its members, or for a large group of workers who do not accomplish very much.
