Consider a scenario where a person encounters something or hears something (experiences something) and he realises that something should be kept as a secret based on ethics or by the nature of something itself. But something is so irresistible to be kept as a secret and eventually the person loses his patience and blurts it out to people.
I would like to know if I can denote such an event by a phrase or a word.
"Mr. X encountered a/an _______ event".
The blank should be filled with a phrase or a term that denotes, an event that should have been kept as a secret, but due to irresistible circumstances, it came into light
Also, the event is not irresistible for a specific person. It is associated with the nature of the event.
I am not able to find an exact scenario to be given as an example. But this is what that person would think about the event when he encounters: Ah! This should be kept as a secret. But how can I? I cannot restrict myself from telling this, and he tells it out.
How would one describe such events as?
