An act of semi-public sexual exhibitionism, especially if performed by a woman.
1. "I knew a girl called Nikki, I guess you could say she was a sex fiend. I met her in a hotel lobby, masturbating with a magazine."
2. Wearing a short skirt and no knickers, while bending over to pick up a book from the lowest shelf in the library is a classic example of doing a Darling Nikki.
3. Slipping your fingers into your vagina under the table, and then slowly having the guy suck the juices in the middle of the restaurant.
an act where post coitus the female leaves while the man is asleep yet leaves her contact info thanking him for the funky time and imploring him to call her whenever he wants to grind.
Dude, I totally hooked up with that chick from the party last night and she hit me with a Darling Nikki.
