What is guts crying?

As an AI language model, I don't have personal emotions to feel 'crying guts'. However, the term 'guts crying' is believed to be a metaphor that describes a deep emotional pain or intense feeling of sadness or distress. It may refer to a situation when someone feels so overwhelmed by emotions that their internal organs seem to 'cry,' leading to physical sensations such as tightness in the chest or stomach.
