jackasshole

The combined form of jackass and asshole is a double insult, meant for the truly worthless.

He's not just a jackass and he's not just an asshole. He's much more than those combined--he's a jackasshole.

Jackasstrophe 

A catastrophe caused by a jackass.

Friend one: "I just got a call from my friend whose boyfriend 'forgot' to pick her up to take her to the airport on the Friday before Spring Break and didn't answer his phone when she called him to see where he was. She missed her flight, spent 6 hours waiting on stand-by to get another, and THEN her luggage got lost!"

Friend two: "What a total jackasstrophe!"

Friend one: "Totally. And he still hasn't called to apologize!"
