Coonskin cap
A female pubic hair style that consists of a large frontal bush with a connecting thin bush that trails over her taint and up her gluteal cleft; thus, resembling the hat fashioned from the skin and fur of a raccoon. The "coonskin cap" was a popular style among women in the mid to late nineteenth century and 1970s, and is commonly seen in retro pornography.
