A totally and completely passive-aggressive JERK who believes the world SHOULD and MUST revolve around his own wants and needs and whims and who therefore has a sick stupid disregard for the universal law of "reaping what you sow" cuz he "thinks" it SURELY could not apply to or negatively impact him because he's too much The S_ _ t!!!

Your current boss.

someone being arrogant, rude, obnoxious, or just a total dickhead....

Your butt hole. Were your shit comes out.

A person in another car who cuts you off to get to the next lane, almost hits you while talking on the phone.

An obnoxious, arrogant, self-centered male who women can't seem to get enough of.

Anyone who doesn't do exactly what you think they ought to do, exactly when you think they ought to do it.

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.
