Jackajoo 

When, in school, you find some tissue paper then wet it then throw it at the ceiling. Then it later falls down on someones head.

"Aww man, i just got Jackajoo'd"

"LOL, i just Jackajoo'd that guy."

"That guys about to have a Jackajoo on his head."

"Hey man, is that like some bird shit?"
"No, it's a Jackajoo."

jackaloon

a publicly acceptable way of calling someone a jackass. someone who recently has done something stupid and deserves to be called a jackass, but there are people around that wouldn't appreciate that and so you simply call them a jackaloon.

"Dude what's wrong with your toaster?" "You have to plug it in first you jackaloon."

Holden Jackaroo 

The Holden Jackaroo is a medium sized SUV produced by GM Daewoo. Holden Jackaroos are most commonly found broken down and abandoned on the side of the road thanks to the ultra unreliable 4JX1 diesel/steam engine that Isuzu decided to fit in them.
Some owners believe their Jackaroo's can be taken off-road despite the fact a Holden Barina puts them to shame both on and off-road, let alone a real 4x4. This common misbelief is due to the vehicles semi-impressive suspension flex, which can be attributed to the soft pine chassis that was jointly developed by Ikea and Isuzu.

Most Jackaroo owners have moved onto more reliable and safer forms of transport such as hitchhiking with Ivan Millat, the rest are broke and stuck with it.

"No we won't insure your Holden Jackaroo. It's not worth anything and won't go anywhere"
"I'm sorry you own a Holden Jackaroo"
"Nothing says failure like a Holden Jackaroo in your driveway".
"No I can't fix your Holden Jackaroo. Get your junk off my property"

Jackaloon

A person that is both a jackass and a lunatic.

There's no reason why a sane person would ever put mayonnaise in their pockets, he is a certifiable jackaloon.
