nightmare sister colleague

A workplace cohort who has taken it upon herself to take on the role of a nightmare sister, finding ways to endlessly embarrass, harass, prank and annoy you to the point of near-insanity.

When I wake up some mornings I find myself breaking out in a cold sweat just imagining the weird and unexpected things my nightmare sister colleague might do to me that day.
