“Referring to a feat that portrays extreme feministic qualities.”
Also on Urban Dictionary, it uses an example of the term as referring to a heterosexual relationship. However, I think this word is perfect for the femme lesbians! If I remember correctly, my roommate was telling me about her girlfriend when I first heard the term. Her and her girlfriend are femme. My roommate, Berri, had used it to describe their overall relationship. Or something to that effect.
I have used the term recently to describe my enjoyment of fine craft beer and looking exceptionally sexy on a Saturday night. “That’s fem-tastic!”
Tip when using this term: If it sounds right, then go with it!
