A spit baby is woman who loves to spit on a blokes cock and balls when she's giving him a blow job. The reason she does this is to keep things well lubed. It also helps to prevent the inside of his foreskin from getting too sore.
I went out with a girl the other night who gave me a fantastic blow job, she was a real spit baby.
