widow's peak

What is the origin of the idiom "widow's peak" and when to use it?

The origin is uncertain. One theory is that the name comes from the traditional mourning attire worn by widows in the past, which often included a black veil that covered the forehead and created a similar point at the center. Another theory suggests that the term comes from the legend of the vampire, as vampires in popular culture are often depicted with a pointed hairline. Regardless of its origins, the term "widow's peak" has been used since the mid-19th century to describe this distinctive hairline, and it has been popularized in literature and film through characters such as Count Dracula and Lily Munster.
