EMILY: That’s a pretty colour. What is that?
LORELAI: It’s called Vicious Trollop.
A fictional shade of lipstick, a joke based on the sometimes bizarre names chosen for lipstick colours. It appears to be a MAC lipstick, Lorelai’s favourite make-up brand, and according to the Gilmore Girls Instagram page, it’s a dark red matte colour.
You can now buy “Vicious Trollop” lip balm on Etsy, but apart from not being actual lipstick, it’s nowhere near the right colour.
