chrome dome
A person who is completely bald, or that person's head. I actually started losing my hair in my late twenties, and I've been a chrome dome ever since! Some women don't care for bald men, but I love my husband's chrome dome.
chrome horn
A car's front bumper when used to nudge or hit the car in front of it, either in retaliation or (in stock car racing) to inform the second car's driver that the first intends to pass. Always be considerate when changing lanes in front of other cars, as aggressive drivers may feel inclined to use their chrome horns to signal their displeasure. Some really aggressive driving by Roberts; he's been putting that chrome horn to use today!
