Omnishambles 

A person or situation that looks like a fuck up from all possible angles.

Originally coined in S03E01 of The Thick of It:

Not only have you got a fucking bent husband and a fucking daughter that gets taken to school in a fucking sedan chair, you're also fucking mental. Jesus Christ, see you, you're a fucking omnishambles, that's what you are. You're like that coffee machine, you know: from bean to cup, you fuck up.

– Malcolm Tucker

Omni-shambles

A prodigiously inept individual, typically involved in the political domain. Just as God is omni-potent and 'all-powerful', such an incompetent is omni-shambolic and 'all-failing'. Coined by Malcolm Tucker, of 'The Thick of It' fame.

I was going to ask if you could help me with my science project, but then I remembered you were the omni-shambles so I asked my step-dad for some money so I could download it from the internet instead.
