1) A lesbian who behaves in a very feminine manner, not so much because she is a femme, but to distance herself from dykedom. These types tend to not even like the word "lesbian" and be very closeted. They tend to run ads that say things like, "Feminine-acting woman seeks feminine-acting woman for romance. No drugs, smokers, or butches." They are also considered irritating by dykes. 2) Synonym for High Femme. (RS)
A lipstick lesbian is a slang term for a feminine homosexual woman who is attracted to another feminine woman, rather than a lesbian who is attracted to a more masculine woman, such as in a "butch and femme"-type relationship. It is also used to describe a homosexual (or bisexual) woman who exhibits feminine gender expression, a female who wears make-up (thus, lipstick), dresses or skirts, and perhaps takes on other characteristics associated with feminine women.
