I gave that bitch so many mushroom marks that her forehead looked like the background of a smurfs episode.

mushroom management 

1. Mushroom Management

Restrict employee access to information and decisions (keep them in the dark).
When information is conveyed, it is incomplete, inaccurate, or full of marketing hyperbole (throw shit on them).

Large, hierarchical, process-bound organizations are frequently guilty of the most egregious forms of "mushroom management."
