When someone you know comes to visit unexpectedly and inconveniently, often staying for a long time, and you can't tell them to leave without being rude.
Yesterday, I was just about to go out, and then the doorbell rang. It was Sally, and she invited herself in and stayed for an hour! It was social terrorism!

Dropping a bomb in the middle of a social situation to make things awkward.
My sister just committed an act of Social Terrorism. She goes, "Ed, why are you so cheap? Even my brother says you are cheap." And then she turns around and goes to the bar, leaving me to clean up the disaster.
