The celebration of the end of the world adapted from the science fiction genre based from the zombie apocalypse. Pointlessly given the name Doomsday by religions and mythologies to make it sound all the more terrifying to people like Thor and Odin. A great time for students to leave their homework for another time and start running for their lives.
Happy doomsday guys! YaY!
