Anatomy: In humans, the rump refers to the buttocks or the posterior portion of the torso formed by the gluteal region; in animals, the rump denotes the hindquarters, including the hips and upper hind leg.

Culinary: In butchery, rump is a primal cut from the hindquarter of cattle and is used for roasts or steaks; rump steak and rump roast are common preparations.

Ornithology: In birds, the rump is the area of plumage on the lower back near the tail, sometimes a field mark.

Politics: The term "rump" is used to describe a legislative body remaining after others have expelled or when a majority has been purged; notably, the Rump Parliament of 1648–1653 after Pride's Purge in England.

Etymology: The word derives from Old English and has historical usage in describing the hind part of an object or animal.
