The Hurley
Simply, while performing fellatio or giving a blowjob, one has a nose bleed. This undoubtedly must happen before the receiver ejaculates and the fellatio performer is still down on the receiver. Also, criteria must be a blowjob in A VEHICLE or train/plane/boat/cruise ship/ etc.
Oh twas a classic teenage fellatio session, in the front seat of a car. The windows were closed and the defroster was one, 100 degrees in the car. When the female blowjob giver was doing what she does best, a terrible thing happened. The sweltering heat mixed with her cold and within seconds of throating him, she had a nosebleed. And thus, the Hurley was born.
