What is a slang word for eggs?

There isn't really a widely used slang word for eggs. However, depending on the context, people might use some informal terms:

* "Balls": This is used humorously, especially in a breakfast context.

* "Jollies": More of a British slang, mostly used to refer to testicles, but sometimes used for eggs.
