Agent Orange

A reference for a person, normally older or elderly from the Vietnam War era, who repels people by not picking up on any social cues, going on rants about themselves and previous time in the war, college, or when they were in their prime. A person of that age range is referred to this when they repel others and hurt those around them like poison by being selfish, disrespectful, entitled, rude, etc. and generally lack friends and social supports. They feel entitled to tell their story and that you should appreciate them and lack empathy or understanding that it may not be a good time for you.
