Shadow-kiss

When your lips touch a surface previously touched by another person's lips.

Person 2: "Yeah, I think so..."
Person 1: "That means I've just shadow-kissed you!!"
Person 2: "bruh"

Shadow kissed

Someone who has passed into the land of the dead but has re-entered the land of the living is said to be shadow kissed as their aura is full of shadows. They often have a psychic bond with the person who saved them.

'I was dead?'

'Yeah, but I saved you. You're shadow kissed!'
