Even though you are right, misusing the term in situations where your one life is either in danger, or where you make extremely dumb decisions even though you know better… is the joke and makes the term so charming for me.
For me it basically translates into : “I am about to do this dumb thing which I already know is dumb, but living my life to the fullest leads me right here”
Interesting hypothesis, would you mind citing some sources for those claims? I never heard of spez being CIA or any of the other rather huge claims you make.
