An act of
masturbation in which, while one pleasures themself, they decapitate themself with a rusty shovel or
dime store
katana at the verge of climax. Then, whilst their head rolls away, they attempt to catch the load in their mouth within the final three seconds of life.
Detective 1: "What do you think
Bill, was this a
murder?"
Detective 2: "Well, judging by the placement of the head and the trajectory of the
wad, I'd have to say that this is autoerotic decapitation."
