We actually have had this thread before, but what goes around, comes around, I suppose.
Mine is complicated. It's German for "The Clever", or so I thought, until a German exchange student told me that the "die" is feminine and "der" would be the masculine, so it actually means "clever woman", which makes sense, since it is the name of a rather obscure German opera by composer Carl Orff (Carmina Burana), whose long title is "The King and the Clever woman".
The name itself was the product of an hour long search one night to try to find a unique hotmail name - something I didn't have to add numbers to.
I'm thinking of changing it, though, since the thought of being a "clever woman" kind of depresses me. Since I'm a guy and all...
