The Higgs-Poofuck Particle
When a person has copious amounts of anal sex, that a seperate cavity is formed within the rectum. Over time faeces build up in this cavity until it cannot hold the pressure any more, similar to a dam break. The coming catastrophe causes an implosion, in which the person is sucked into a vortex until they are one tiny poo particle. This shit molecule has the density of dark matter. A phenomenon in which only 1 in every 1,672,200 anal sex havers experience.
Well would you look at that, Scott imploded into The Higgs-Poofuck Particle. Could have seen that one coming.
