rulemonger

Why this word is great

RULEMONGER — [Noun] A person who is excessively or pedantically concerned with enforcing rules. From rule (from Old French reule, from Latin regula, "straight stick, bar, ruler") + monger (from Old English mangere, "merchant, trader"), here used in the sense of "one who deals in or promotes something." Unlike a "stickler" (who demands precision in principle) or a "bureaucrat" (who follows procedure by necessity), the rulemonger enforces with the zeal of a convert and the imagination of a clerk. It is the librarian who shushes a cough, the neighbor who reports an overgrown hedge to the inch, the volunteer crossing guard who halts traffic long after the children have passed—each a minor priest in the temple of control, mistaking the scaffolding of society for its soul.
