The most beautiful color of hair, a reddish hue. Makes the most ugly girl sooo hot. It is a compliment, and it is only used to talk about the color of head - hair. Red hair can have a goldish tint, a brownish tint, a orangie tint, or other. It is very pretty.
RIGHT WAY TO USE IT:
Evan: Do you like the new girl, Mary-anne?
Jorge: Yeah. She is so hot with her ginger hair!
Sarah: Ewwwwww, you stink, you ginger hair. Your pubes are ginger, and you STINK!
Emillie: *blushes and runs away*
