Essentially "jackass" but used in the context for the results left behind of the way someone acts.
This can involve vandalism, pranks, or just generally being an idiot or incompetent to the point of really messing up things around them. Can also mean when someone else gets falsely accused for their inability or ineptitude.
There are always consequences involved and some degree of punishment for these acts as there is always a clear trail of destruction left behind.
From the root word "jacked" or "jacked up", which have varying definitions, based on the context.
The noun "jackery" is the extent to which, or the way in which something(s) or someone is jacked.
T: This bike is so fucked up. Everything is broken or wrong.
E: Ya dude its totally jacked up.
