Cumberg
When a person locked inside a box or case with no possible escape or way to get help starts masturbating because they have nothing else to do. They just keep jacking off while the case just keeps filling up more and more with cum. Even when they realize they're going to drown, they just keeping jacking off until they're completely encased in cum. In 700,000,000 years, when future man discovers him 150 feet beneath the surface of the Earth, the case has completely rotten away yet the cum remains, frozen solid. They crack open the petrified cum to release the now primitive man within like breaking open an iceblock to release a neanderthal. This solid cum, encasing a man like a fly in amber, is called a cumberg.
