"Red wings" is a colloquial term for the act of performing cunnilingus on a woman while she is having her menstrual period. The term originates from the idea that her partner's bloody lips and face resemble a red bird’s wings after they perform cunnilingus on her.
A person who performs oral sex on a woman during her period is also said to have earned their "red wings." The term originated amongst the Hells Angels but has since gained popularity. Less commonly, a person is said to have earned their red wings after engaging in any kind of sexual activity with a menstruating woman.

The author Hunter S. Thompson is believed to have made the first public mention of red wings in his 1966 book, “Hells Angels, A Strange and Terrible Saga.” In the book, Thompson discusses the different adornments the gang members used to differentiate themselves from other members of society. To gain red wings was seen as a rite of passage.

While the practice of red wings is rarely written about, it is an act that some couples engage in.
