princess by day, slut by night 

A 'Princess' is an adult woman who is submissive to men they consider to be dominant over them (such as Daddies). The point of being a Princess is the love of being admired, listened to, respected, honored, served, and pampered. The extension of that role is the 'Princess by Day, Slut by Night.' This complementary side of the 'Princess' is when after being completely cared for and treated like royalty by her Dominant, that she willingly becomes a dirty slut to likewise honor in kind whatever her man is in the mood for afterward. Her ability to be the dirty, nasty slut that he loves is dependent on his honoring her wishes and providing for her beforehand.
Her: "I think maybe we should go to fav bistro for lunch... What do you think?"
Him: "Of course my Princess by Day, Slut by night, whatever you're hungry for sounds fantastic."
(later)
Him: "Since the moon is full, maybe we should drive up to the secluded canyon and hike naked up to that one rock that I like to bend you over?"
Her: "Do you want me to paint my tits and ass with that glow-in-the-dark body-paint again?"
Him: "Do it with neon green this time!"

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
