This game asks people to summarize a complicated topic in twenty words or less. For example, calculus could be summarized by “what happens to math when things change or are broken into small parts then put back together”.
I will now choose another word. Someone else (or many other people) has to briefly summarize it and suggest another complicated topic. Subsequent posters can choose any topic to summarize that was previously suggested by any poster in any above post, so multiple answers are fine.
So! Does anyone want to briefly summarize “Donald Trump”?
