The type of girlfriend who would reply to everything her beloved tells her (including compliments) with sarcastic witticisms; who would deliberately speak in riddles and foreign languages she knows he doesn't understand to amuse herself at his expense; who would arrange complex pranks and April Fools jokes on him, and would not waste any opportunity to demonstrate that she is smarter than him. In detective couple series, she would usually figure out the mystery before her boyfriend/husband does, and keep him Locked Out of the Loop until The Reveal.
Nevertheless, they seem to be a very loving and mutually understanding couple... This is because, unlike Bastard Girlfriend, she actually has a heart of gold, upholds a strong moral code, and cares for her beloved very much. Once things get really tough, she would drop the "trickster" facade in an eyeblink and give him all the love and support he needs. Basically, the primary reason she puts on the facade is because she knows that though her boyfriend/husband would never admit to it, this is exactly what attracts him to her. Besides, with a girlfriend like her, you will forget what the word "boredom" means.
- The Spice and Wolf character Holo enjoys teaching Lawrence (her future husband) about human nature, often by showing off her skills in manipulation. Even when flirting with him, she speaks in indirect terms like "Women enjoy men's jealousy" and lets him figure out their personal subtext.
- C. C. from Code Geass is very sarcastic and often keeps secrets from Lelouch, and there are implications of a romance between them.
- In the 2012 Spanish movie The Body, Mayka Villaverde, the main character's wife, has pulled many pranks on her husband, including jokingly saying "No" at the wedding altar and pretending that she fired him from her company. It later turned out that she and her husband were not such a loving couple at all, when he cheated on her and then poisoned her to get her money.
- The eponymous protagonist in Amélie begins as this for Nino; she plays elaborate cat-and-mouse games with him without even revealing her face. It's mostly due to shyness though.
- River Song from the Doctor Who series is this for the Doctor himself. She really enjoys teasing him and withholding information from him (as a time traveler, she has to conceal information about the future to avoid a time paradox, but she turns it into a way of amusement); "I know something that you don't" is basically her motto.
- Emmie Reese, the main character's wife from The Harry Reese Mysteries series by Robert Bruce Stewart. She simply loves all sorts of pranks, surprises and schemes, and keeps many secrets from her husband.
- Amy Dunne from Gone Girl is an extremely dark subversion of this trope. She really likes to mislead other people, including her husband Nick, but instead doing it just for fun, she's very serious about it, and she does intend to ruin their lives.
- The Merchant of Venice: Portia, who arranges a complex prank on her fiancé Bassanio. First she gives him a ring and makes him promise that he won't give it to anyone. Then, disguised as a male lawyer named Balthazar, she saves his friend Antonio in court and asks for "himself" this ring as a sign of gratitude. When he comes back to her after that, she teasingly pretends to be angry and accuses him of infidelity, then takes out this very ring and says that she slept with Balthazar to get it back... And finally she admits that she was Balthazar herself.
- Arline Feynman, the famed physicist's first wife, was very much this. It is really indicative that some time after her tragic death, he met her in a dream, and she told him:
I fooled you. I was tired of you, so I cooked up this ruse so that I could go my own way. But now I like you again, so I've come back.
