A fart in bed that is released prior to your parter getting under the covers. The gas from your fart is trapped within the tighly tucked sheets and no smell is able to escape. When your partner goes to get into bed, they untuck the sheets, thus allowing the trapped stench of death to escape into the fresh air and blast them in the face.
