Undercover Ginger

One who does not show visible signs of being a ginger (ie red hair or freckles), but days of not shaving reveal red facial hair. This allows the individual the ability to hide ones gingerness from the world.

By simply shaving his red beard, Tom was able to hide his true ginger identity and go about his day as an undercover ginger.
