unchivalrous

If someone is rude and inattentive, they're unchivalrous. It's most common to describe men as unchivalrous, particularly when they behave impolitely toward women.

This adjective, like its opposite, chivalrous, is a bit old-fashioned, but it's still used to describe men who don't act gallantly — or the ungallant act itself. Both words come from chivalry, the medieval code that knights lived by. If a guy doesn't act the way a gallant knight would, letting the door slam in your face, he's unchivalrous.
