- Everything a living animal could do to destroy and to desecrate bed and walls had been done. […] A canister of flour from the kitchen had been thrown at the looking-glass and lay like trampled snow over the remains of a decent blue suit with the lining ripped out which lay on top of the ruin of a plastic wardrobe.
- Any of various cylindrical metal receptacles usually with a removable close-fitting top.
- A special short range antipersonnel projectile consisting of a casing of light metal, loaded with preformed submissiles such as flechettes or steel balls. The casing is designed to open just beyond the muzzle of the weapon, dispersing the submissiles.
