Also known as a "neck j." It is a sexual maneuver where the male first forcefully slices off a woman's head and then disposes of the body. He next takes the head and (after opening the eyes and staring into them) he places the dead lady's head on his penis and begins to bob her up and down until he cums. Depending on the size of said man's cock, the perpetrator may have to "hollow out" the womans neck so his hard penis will fit in there.
Yo dude, did you hear? Stephen gave Leigh a neck job last night and now her funeral is next Wednesday.
