Inaccurance 

Inaccurate to such wild extent as to make one piss themselves out of raw fear. Inspired by the Richard Sandoval accounting department and known in accounting circles elsewhere since.

The inaccurance of that report blew my mind. I don't think I can actually use it.

proportionally inaccurate 

A person who when you see them looks built strangely. This does not apply to people with any form of disability or a midget. Someone who is proportionally inaccurate looks as if when god was creating them he skipped a few steps or messed up when doing the math to find the right proportions.

My math teacher kinda walks funny. I think it may be due to her proportionate innacuracy. Shes proportionally inaccurate

MC Historical Inaccuracy 

A rapper created by Jon Lajoie, a comedian. He tries to drop historical knowledge in his bars, but he is wrong on all of them.

"Yo I'm MC Historical Inaccuracy
I drop lyrical bombs like Hiroshima in '73
I write rhymes like Shakespeare when he wrote Anne Frank's diary
Which is about the civil war of 1812 in Germany"
