It's my phrase for the slightly scary ladies who work on the Bobbi Brown counters and follow the tao of Bobbi to the absolute letter.
I had a run-in with one a few years ago back when Dickens & Jones still existed. I wanted to buy a mid-toned shade for my eye crease to contour, but apparently;
"Bobbi does not believe in contouring, she believes in a base shade, a lid shade and a liner shade."
She kept repeating this, until eventually we agreed to pretend that I wanted said shade for a lid/liner colour, and would never use it to contour my crease.
I do like Bobbi Brown (honestly) because she makes makeup accessible to many to whom it was a frustrating mystery. I do remember when as well as contouring she didn't believe in shimmer on the cheeks or any bright colours though, and how times have been changing!
The concealer and corrector are very good for very dark circles, Bobbibot or not.
