Used by a character in Anne Rice's book Blood Canticle; Rowan Mayfair says the word describing Blood Children, as the vampires. Lestat explains that he (with permission and love from Tarquin "Quinn" Blackwood, Mona's-current-lover) 'done it' to Mona Mayfair, as in, turned her, into one of these blood children.
Lestat (should be a familiar face) has been say to 'Look like an angel, and talk like a gangster.' In this book.
Blood children, vampires, blood-suckers. Those who live forever in a permanent state of beauty.
What some says or thinks when they are killing mad. It means that you will spill so much of there blood and so violently that some of it will land on the moon.
Those gangbangers killed my homey. There will be blood on the moon!
