grey goo

A mass of world dominating self-reproducing nanobots. Grey goo common end-of-the-world scenario, where malfunctioning nanobots reproduce without inhibition, consuming any available raw materials.

Grey goo can also be used to describe any number of warm breakfast cereals, such as oatmeal, cream of wheat, or grits.

Man, when national labs release grey goo, I'm heading off to the mountains in Alaska before I get consumed alive.

grey-herring

a problem area that unexpectedly arises and has the potential to reveal one's incompetence in a meeting. Grey Herrings occur predominantly in the calvinus stupidicus species. Grey herrings are stress-inducing and evoke compulsive lying.

calvin was nervous going into the meeting because of the grey-herring rumored to be swimmin around the switchyard.

grey-mouse-woman syndrome

A totally mediocre, not ugly, not beautiful, utterly forgettable woman who posts amazing pictures of her pathetic life on social media pretending that she’s someone else.

smackhead grey

this is a colour to describe the grey garments worn by the generic lower class delinquent chav and NPC across the entirety of the UK.

the worst items of clothing to be this colour are: joggers, leggings, and hoodies.

if you encounter someone wearing smackhead grey joggers / leggings, let it be known that this person is devoid of all personality and probably watches love island regularly.

there are so many people at my college wearing smackhead grey - when will they develop a fashion sense? will they stay wearing 11°, nicce and gymshark?
