look up any word, like doxx:
A person whom while able to minimally function in society, hold a job (at varying degrees of success), feed, clothe & house themselves still remain a disaster at nearly all other personal & social aspects of life.

They are your severely disturbed, paranoid and/or inappropriate coworkers, family & friends, yet remain gainfully employed, operate vehicles daily and manage to not starve to death.
Because of their multiple failed relationships and substance abuse charges, Brittney & Lindsey remain the poster children for the functional dysfunctional.
