Ginger Fever is the condition that heterosexual men who are sexually attracted to redhead women (or at least women with Auburn hair) have. Both redheaded and non-redheaded men can have Ginger Fever. Men with Ginger Fever are often fascinated by countries with higher proportions of redheads including Ireland, Scotland and some parts of Mainland Europe.
Ginger Fever is not to be mistaken for Bagpipe Queen, which applies to homosexual men who are sexually attracted to redheaded/Scottish men.
