Today, I opened a coconut. When I opened it, it sounded angry. After taking a sip, the aftertaste is a little sour, and the coconut juice is yellow-green. See the picture, this coconut.

According to your description, this coconut may not be very fresh or has gone bad. The normal color of coconut water should be transparent, while yellow-green water may mean that coconut has deteriorated or been polluted. In addition, the smell of coconut when it is opened may be due to the release of gas inside the coconut, which may also indicate that the coconut is not very fresh.

In order to ensure your health and safety, it is recommended that you do not drink this coconut water, and it is best not to eat coconut meat or other parts. If you have drunk this coconut water and have any discomfort symptoms, such as vomiting and diarrhea, it is recommended to seek medical advice as soon as possible.
