a friend of mara
A friend of Mara is a sapphic person who wants to know if you're a dyke too. It's also used in the She-Ra fandom like it's a secret code.
At the bar, my friend said, "Are you a friend of Mara?" I said, "No, I'm a friend of the drink." She said, "That's just a fag disguise."
My coworker asked me, "You're a friend of Mara, right?" I said, "No, I'm a friend of the coffee." He said, "That's just a lie."
My friend said, "You're a friend of Mara, aren't you?" I said, "No, I'm a friend of the weekend." She said, "That's just a fag excuse."
