Cullawayskuhl-uh-weys

n. The scattering of memories that your brain is actively forgetting at any given moment, erasing them one by one with no input from you and no knowledge that it's happening at all--which means that when you wake up in the morning, your past will feel imperceptibly altered, with no trace of what you ate last week, a party you attended ten years ago, or the first real conversation you had with your grandfather.
