A term used for describing pathetic, worthless, and/or hopeless work. Derives from Latin 'plebius' (which means 'of common people') and carries elitist connotations from the user of the word.
PYTHON-532 on the MongoDB bug tracker is an example of utter plebbery--some newb who shouldn't have had commit rights wrote terribly insecure code.
An individual who has been esteemed a step ahead from just a regular pleb. Such a position can only be acquired by being so unbelievably plebby such that it impacts the members around him/her. Only an unpleasant plebberchini can affect a society of non-plebs to obtain pleb attributes.
Look at Liam, he has become such a Plebberchini these last couple of days.
