Rubber-necker

I suppose that fellow was a rubber-necker, and got killed peeping over the trenches.

He is a great "rubber-necker." What he don't see aint worth looking at.

We are taught the importance of hygiene of the mouth, of the body, and of the hair, but little concerning the nose, which is the "rubber-necker" which is expected to discover any laxity of cleanliness of other parts of the body or the air around us.
