scrotocrat
someone (mostly, if not all, male) controlled by the scrotal area, that promotes sexism, bigotry, xenophobia … They are right and you are wrong. They promote themselves at the expense of others and refuse to accept blame for errors (whatever the magnitude) and never apologize for their screw-ups. Typically, scrotocrats have small hands and use scotch tape to control ties.
Donald Trump is the chief scrotocrat in charge
