The idiom "have your thumb up your ass" is a vulgar way of saying that someone is being lazy or not doing anything productive. It means that the person is wasting their time and not making any effort to accomplish anything.
This phrase is often used in a negative context to criticize someone for their lack of effort or productivity. For example, if someone is supposed to be working on a project but is instead sitting around doing nothing, you might say, "Why do you have your thumb up your ass? Get to work!"
