What is have your cake and eat it too?

"Have your cake and eat it too" is an idiom that means to enjoy the benefits of two or more mutually exclusive options, which is usually impossible. It implies wanting to have it both ways, and get the advantages of a situation without having to deal with the disadvantages.

Here are some examples of how the idiom is used:

* "You can't have your cake and eat it too. If you want to travel the world, you'll have to save money, and that means giving up some luxuries." This implies that you can't both spend money on luxuries and travel the world, as you need to save money for travel.

* "He wants to have his cake and eat it too. He wants to work from home, but also be able to attend all the company events." This means that he wants the benefits of working from home (flexibility) and also the benefits of working in the office (social interaction and events), which are mutually exclusive.

The idiom is often used to criticize someone who is being unrealistic or greedy.

It's important to note that the idiom is often used ironically, meaning the speaker actually thinks it IS possible to have your cake and eat it too, or that they are being sarcastic.
