From the words "scary" and "vagina"= "scaryginer".
A scaryginer is a ferocious beast that is both angry and untamable. Anatomically, the presence of excessive inner labia creates a roast beef like appearance in the female genitalia that is both grotesque and unattractive. The double headed hydra of a furginer combined with a scaryginer is something that nightmares are made of. The combination of a smoothginer and a scaryginer is a leading cause of TBD (Temporary Blindness Disorder).
Scaryginers are a phenomanon that seems to be evenly distributed across the full spectrum of "giners", ie., younginers, funginers, smothginers, etc...
