I'm assuming you're not referring to the oval tool people use to eat soup or cereal with (or stir their tea, or, if they are blasphemous people who don't own cake forks, eat cake with). If you are referring to spoon theory, as far as I understand it, spoons are an inofficial measurement unit for a person's energy. Basically, if you take all of your energy that you have at your disposal, and then you go take a walk, that may cost you one spoon of energy. Another person, who maybe has chronic pain, may need a lot more spoons to take the same walk, because their pain makes it more exhausting. Sometimes people say they "don't have enough spoons" to do something - that means they feel like something is too exhausting for them to do, either in general or at the moment. People also say they are "out of spoons" - that means they are tired and don't have energy left to do anything at all. The use of the term spoon in this way is common among people with disabilities and/or chronic physical or mental illnesses. People who use this term are often called "spoonies" and also refer to themselves that way.
