The worst kind of person. You cannot fully construct a meaning that fully encompasses what this vicious insult means. If you're an asshole, you are disgusting, loathesome, vile, distasteful, wrathful, belligerent, agoraphobic, and more. Assholes are human fecal matter. They are the lowest of the low. They transcend all forms of immorality. It is the very worst of insults; to be called an asshole is to have your very soul ripped apart and shat on. I say that the word "asshole" is the worst cussword of the english language, worst than fuck, shit, and cunt combined.
