"Lazy Blow Job". It is when a female gives a blow job while resting her head on the guy's stomach. She may take occasional oral breaks, and switch on and off with the hand. Not as good as a traditional blow job, but still quite enjoyable.
Female: "I'm tired, let's go to bed." Male: "Ah man, how 'bout a quick LBJ?" Female: "Allllright."
