hard-nosed, soft-nosed, dum-dum
Someone who is hard-nosed is stubborn, obstinate, or unyielding, tough, uncompromising. This slang sense has been around since the late 1920s. The OED records a 1927 theater program glossing the term, indicating that the usage was not completely familiar. And in 1928 the journal American Speech records it as carnival slang ("Contributor’s Column,” American Speech, Vol. 3, No. 3, February 1928, 253–57). But where does the term come from? What does an impenetrable proboscis have to do with being stubborn or unyielding?
The answer is that the term comes from the world of the military and munitions. It started out as a retronym for a type of bullet. In the late nineteenth century, ammunition makers started producing bullets that deformed upon impact, increasing the damage caused. The most famous of these soft-nosed projectiles were produced at the British arsenal in Dum-Dum, India.
