Kissed by fire
Kissed by fire is a term used by the free folk to describe people with red hair. They consider red hair to be lucky and very attractive. It is rare among the free folk and those who have it are said to be kissed by fire. The spearwife Ygritte is considered common looking by Jon Snow at first but when he joins the free folk he soon learns that amongst the wildlings she is considered a great beauty due to her red hair.
– Jon Snow, to Ygritte
You’re kissed by fire, remember? Lucky.
