> How many times have you said something along the lines of “I will kill you if you put that picture of me on Instagram!”

But his threat was much more graphic and specific. How many times have you e.g. emailed your friend’s whole family with a message along the lines of “If you post that picture online I will eviscerate you and then hang you from your mother’s dining room ceiling by your intestines as a warning.”

That is not normal friendly exaggerated banter, and would be pretty hard to play off as a joke.
