"This is the way the world ends
Not with a bang but a whimper"
[T.S. Eliot, "Hollow Men," 1925]
Bang (bāng, bäng), Bernhard Lauritz Frederik. 1848-1932.
Danish veterinarian who discovered Brucella abortus, the agent of brucellosis in cattle and of undulant fever in humans.
bang up
Damage, injure, as in Banging up the car a second time will make Dad very unhappy, or Mother fell down the stairs and was all banged up. The verb to bang alone had this meaning from the 1500s on, up being added in the late 1800s. In the early 1800s it gave rise to the colloquial adjective bang-up, for excellent or very successful, as in David did a bang-up job baking the birthday cake.
