a person who has pale skin, red freckles, and red hair (ginger) who is seen in the daytime, which is a rare occurrence because gingers prefer to be nocturnal and only go out at night because the sun hurts their sensitive albino skin.

"The little girl screamed when she saw the daywalking ginger walk in front of her."
