A combination of jackass and asshole, with an implied "ass".

Also a less vulgar insult used in mixed company.

Portmanteau of "Jackass" and "Asshole".

Originated as a name by radio personalities Kevin and Bean (from KROQ-FM in Los Angeles) as a way of calling somebody a nasty name without actually breaking FCC edicts against foul language.

To clarify, it was Jimmy Kimmel and Adam Carolla who invented the word while they were working on the Kevin & Bean morning show on KROQ.
Ah, those were the days.

1. A combination of the words "jackass" and "asshole". Often used on the radio, because the FCC lets it through. Assumed to have the same impact as "fucktard" or similar words.

2. Jackhole Industries -- the production company of Daniel Kellison, Jimmy Kimmel and Adam Carolla. They produced shows such as "The Man Show" and "Crank Yankers."

more than a jackass, more than an asshole--he's a jackhole.

A jackhole is an elusive creature who has been known to terrorize governmental agencies, and more specifically known to terrorize police departments by causing small nuisance damage to there buildings and vehicles.

A mixture between a jackass and an asshole. It is way better than both because it sounds much more offensive and no one knows what it means. It can be used in many different forms.

An undesireable person, a jerk.
