Apocalypse sex refers to the passionate sexual activities that some individuals partake in just before a possible apocalypse or other global catastrophic event. This type of sex is often very passionate or frenzied, yet usually only involves physical pleasure without any emotional connection. Before possible apocalyptic events, some individuals actively seek partners for wanton sexual encounters. Individuals looking for apocalypse sex may explore kinky fetishes, or even engage in unprotected sex.
The idea behind apocalypse sex is that the world could possibly be coming to an end, so people don't need to worry about the consequences of their actions and may as well enjoy the time they have left. Apocalypse sex is a common trope in media.
Apocalypse sex may also be called end-of-the-world sex.
