to Iob; is to use the ring and middle finger, of the left hand (important to not use the right hand), and pleasure a female. Origins of a young man who invented the Iob, not the first to perform it, that being a close friend of his, but the first to perfect it.
Ricky walks into a party and sees a group of bitches just chillin. So he walks up and grabs and her and says "bitch it's not your day" performs The Iob, fast and well. Girl is left pleasured and wanting more.
