Acronym for 'Jump In Game', when a player repeatedly uses the jump button or key to constantly jump for no reason whatsoever.
Once upon a time this was commonly referred to as 'bunny hopping' which was used as an exploit in
Counter Strike. These days, this behaviour is most prevalent in online
multiplayer games such as WoW where players will be seen 'jigging' around Ironforge just
because they can.
Some gamers prefer solo-jigging. Solo-jigging can be enjoyed in single player games such as Oblivion.
