Oh yeah, I know someone who named her kid Khaleesi. Oh dear.
But let's be honest if you're going to call your kid Khaleesi that kid was always going to grow to be a stripper. Poor kid. She is going to be in high school before she learns how to lean to spell it.
Just to be nit picky: Khaleesi was a title, like queen or chieftess. The character was named Daenerys Targaryen. So they would technically have not named their child after a character.
Daenerys met several former khaleesi's when she was brought before the Doth Khaleen. While at this point, their husbands had been killed and they had given up the title of Khaleesi and adopted the new title of Khaleen, they were at one point each a khaleesi.
The only one I can remember by name is, Ornela, the one that befriended Daenerys.
