Niggerhead

In several English-speaking countries, niggerhead or nigger head is a former name for several things thought to resemble a black person's head (cf. "nigger").

The term was once widely used for all sorts of things, including nautical bollards and consumer products including soap, chewing tobacco, stove polish, canned oysters and shrimp, golf tees, and toy cap pistols among others. It was often used for geographic features such as hills and rocks and geological objects such as geodes. The term appears in several US patents for mechanical devices prior to about 1950.
