Definition from Urban Dictionary
azzhat; (plural) azzhats: noun (pronounced with the "z" sounding like an "s" but not quite enough to actually be accused of saying "ass")

Anyone so hateful, chauvinistic, bigoted, etc. that they should wear their ass for a hat. Usually, but not always used in reference to someone who is willfully ignorant, hypocritical, and/or has extreme homophobia, religious intolerance, or fascist ideology.
POTW = Pigeon of the Web
