Gaelic name for "Beautiful Girl." Cai is the term for beauty that is both physical and spiritual, unlike álainn, which just means physical beauty. Leen means little girl or small child.

In Irish folklore, the name Caileen has been used to represent a girl who is greatly unaware of her own worth. She is beautiful and kind but unaware of it, often helping and befriending people of a "lesser status".
Eric: If I ask her out, do you think she'll say yes?
Bri: It's Caileen we're talking about! She'll probably say yes and be shocked why you would even want to go out with her!
Eric: Are you kidding me? She's beautiful.
Bri: Try telling her that...

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.
