An act of intimacy where a man puts fresh mint leaves up a woman's butthole and then proceeds to fish them with his tongue. The name derives from the popular 'thin mints' girl scout cookies.
I just plucked fresh mint leaves from my nana's herb garden and then used them to give my woman a dirty girl scout.
Mix equal parts vodka, Kahlua and Bailey's and pour over ice. Pour the same amount of Creme-de-menthe down the center of the glass. Looks gross, but tastes delicious!
