ARBS

ARBS : Noun : acronym for Angry, Racist Bag of Sins or (alternate) Angry, Racist Bag of Shit.

A person who is unreasonably and illogically permanently attached to a stance of racial bigotry, and who takes every opportunity to publicly rant or take official action against others of different races than his own. A snob of the first order, an ARBS is typically found in government elective offices and in upscale neighborhoods scattered throughout the country.

Attorney General Jeffrey Beauregard Sessions is a real ARBS, and so are the rest of his pals in the Administration.
