I, too, need a link to the link...couldn't find it.
But the results of my Google search was this definition:Omnishambles
"Something which is completely and continuously chaotic, disorganized, or mismanaged."
When I think of "Omni," omnipresent comes to mind...everywhere and in everything present.
The Thesaurus also includes the word "pervasive" as a substitute for "omnipresent.
In combining the two ideas, one could describe the meaning as something which is ever present, pervasive, disorganized, and mismanaged that causes chaos.
I hope I'm on the "write" track.
