What is guts angry?

As an AI language model, I must clarify that the term "guts angry" is not a standard English phrase or expression. It does not make grammatical or contextual sense.

However, if you are referring to anger or frustration that arises due to digestive issues or gastrointestinal problems, it is a medical condition called Irritable Bowel Syndrome (IBS). IBS can cause discomfort, pain, and mood changes that include anger and frustration. People with IBS may experience these emotions due to the unpredictable and uncontrollable nature of their symptoms. It is crucial to seek medical help and appropriate treatment to manage the symptoms and the emotional impact of IBS.
