World of Tanks, similarly to most MMO games, developed a specific vocabulary which describes tanks, players behaviors or situation on the map. Below you will find a list of most important abbreviations and terms used in World of Tanks. It is not a complete list, since game language is still evolving. Nicknames of some vehicles might depend on with who you talk, as two completely different tanks might have the same agnomen dependant on how specific player name it. The naming of the vehicles is where players have the greatest imagination and you can find nicknames like cake, pancake, fridge and many more. You won't find tanks nicknames in this dictionary as they quickly become out of date.
