I'm working on a SC2 glossary for the official thread. Am I missing anything major?
# Pool - eg 6 Pool, 13 Pool, etc. Refers to number of drones made before building a Spawning Pool. Variants of this term extend to other races, eg 10 Depot, 9 Pylon, etc.
_v_ - Refers to possible race matchups. eg, TvZ = Terran vs Zerg. PvP = Protoss vs Protoss.
APM - Short for Actions Per Minute. Refers to the number of clicks and button presses that a player performs in a single minute. Used as a measurement of a player's speed.
BM - Short for Bad Manners. Can refer to "rage quitting", insulting an opponent, etc.
Build Order - A general term to refer to the timing as to when certain structures and units are built.
CC - Short for either Command Center or Cybernetics Core.
Cheese - Refers to high risk/reward early game strategies, sometimes viewed as unorthodox. Most successful against newer players. If a cheese strategy fails, then the player executing the cheese usually lose. eg. Photon Cannon rushes, "Proxy" Gateways, "6 pool", etc.
Cracklings - Refers to Zerglings with the attack speed upgrade.
Dancing - A "micro" technique. Refers to a player attacking a unit, moving away, attacking, moving back, attacking, moving back, etc. Meant to maximize the damage given to a player while minimizing the damage received. May also refer to "getting down with it", or "doing a little jig".
FE - Short for Fast Expand. A strategy of building a mining expansion very early into the game. Most commonly associated with Zerg.
Gate - Short for Gateway. Not to be confused with Stargate.
GG - Short for Good Game. Most often said by a player when he concedes the match. If a player does not declare "GG" before leaving a match, or says it first when not intending to concede, it can be considered "BM", or rude.
GL HF - Short for Good Luck, Have Fun. A common greeting at the beginning of a match.
Harassment - Using hit-and-run attacks to damage, but not destroy, an opponent. Important units and structures are generally the target of harassment the most. For example, a player might "harass" an enemy by sending mutalisks to destroy a player's workers.
Hatch - Short for Hatchery.
Hydras - Short for Hydralisks.
Lings - Short for Zerglings.
Lots - Short for Zealots.
Macro - Refers to actions performed by the player that is centered around a player's base. "Macro" actions include things such as building units, building structures, researching upgrades, expanding, etc. A player with good macro is a player that manages their resources well.
Micro - Refers to actions performed by the player when he is controlling his army. Micro actions include focus firing, "dancing", getting units into position, "harassment", etc. A player with good "micro" generally gets to most out of their units.
MMM - Short for Marines, Marauders, and Medivacs. Common strategy of using a mass of basic Terran infantry units with healing and mobility backup from medivacs.
Mutas - Short for Mutalisks.
Proxy - Refers to building structures close to your enemy, usually far away from your main base. In the early game, it allows faster rushing, but is more risky if the rush fails. Protoss may build "proxy" pylons close to an enemy to allow for faster warp ins.
Rax / Racks - Short for Barracks.
Rines - Short for Marines.
Robo - Short for Robotics Bay.
Speedlings - Refers to Zerglings with the speed upgrade.

Ultras[/i] - Short for Ultralisks.
Wall Off - The strategy of building structures and units at your base's choke point to help guard against early rushes. For Terran, this usually means 2 supply depots with a barracks. For Protoss, this usually means making the choke even smaller with structures and then closing the choke with zealots in the hold position.
