Jumping is the act of entering a tall building and committing suicide. Jummping was used early in the game when those wanted to play only as a zombie would get revived by survivor players. At the time, the ability to chose to reject a revive was unavailable so these players would enter buildings and jump from them in order to become a zombie again. Later in the game, jumping became a way to "cheat death" in order to have a low kill-death ratio. Instead of the possiblity of being killed by an enemy group, some players would jump off a building instead. Jumping is also used, by Vampires, as a means to "hide" while regaining AP or logged off.
