BAM Box: BAM stands for "Build A Minifig" Many LEGO stores have an assortment of minifig parts and accessories separate from the Pick-A-Brick wall. There is a plastic container (the "box") that holds 3 minifigs. A BAM Box of 3 complete minifigs can be purchased for around $10.

Collectible Minifigure: LEGO released the first series of Collectible Minifigs in the first half of 2010. Unlike most LEGO sets, the Collectible Minifigs come in a small bag that contains just one minifig and its accessories. Each series contains 16 minifigs. The small bags are not see through, so the idea was that a collector would have to randomly buy bags and/or trade with other collectors to get all 16 in a series. Many in the LEGO community, however, have found various ways around the random buy method.
Color Change: The color change occurred in late 2003, when the original dark and light greys were replaced by bluish shades of grey (dark bley and light bley), and the older brown was replaced by a redder shade of brown (reddish-brown).
CUUSOO: The LEGO CUUSOO (now LEGO Ideas) program is an opportunity for fans to promote their own model for a chance to have it produced as an official LEGO set. In order to submit an entry, one must upload an image and description of their proposed set. Users can vote to support models on the CUUSOO website. Once a model reaches 10,000 votes, it is reviewed by TLC, and if it passes, is produced as a set.
Dark Age: A dark age is the period in an AFOL’s life when LEGO products are temporarily set aside for other interests. Dark ages typically occur from sometime in the middle teen years to sometime in adulthood. Due to the fan community developed online as well as the formation of teen-friendly LUGs, dark ages are becoming less common.
Dark Bley: Dark bley refers to the bluish shade of dark grey which, in 2003, replaced the older, browner version of dark grey in LEGO sets. Bluish + Grey = Bley

Footprint: This is the amount of table space that a MOC takes up. A building may be 1 foot, 3 inches wide by 1 foot, 9 inches long, but the landscaping or baseplates that it is built on makes it take up a 2X3 baseplate footprint. The coordinator for a collaborative area will often use the footprint sizes of the MOCs that people are bringing to design the layout on the tables beforehand.
Great Ball Contraption: A great ball contraption (or GBC) is a collaboratively built LEGO machine. Each module takes LEGO soccerballs or basketballs into one end, transfers them to the other end, and then passes the balls off to the next module.

LEGO Ambassador: LEGO Ambassadors are volunteer AFOLs who work with The LEGO Group in order to foster communication and collaboration between the company and the LEGO enthusiast community.
LEGO Group, The: The LEGO Group (or The LEGO Company, or TLC, or TLG) is the official name of the company that produces LEGO products. LEGOs: There is no such thing as LEGOs.

Microscale: Microscale (or microfig scale, or pocket model scale) MOCs are any MOCs that are built in a scale much smaller than minifig scale. Often, microscale MOCs are built accoding to a onestud- brick = one-adult-human scale, although this varies.
MINDSTORMS: MINDSTORMS is a series of LEGO products which combine programmable bricks with motors and technic elements in order to create LEGO robots. MINDSTORMS products have been used by schools and other programs in order to teach the fundamentals of robot design and control.
Minifigure: Minifigures (or MFs, or minifigs) are the figures most often found in LEGO sets today. Typically approximately four bricks in height, minifigures have interchangeable hands, hair, legs, heads, torsos, and accessories.
Minifigure Scale: Minifigure scale (or minifig scale) refers to LEGO creations that are built to the scale of minifigures. Thus, minifigure scale is approximate 1:48.
My Own Creation: My own creation (or MOC) refers to any LEGO creation designed and built by a LEGO enthusiast.
Nanoscale: Nanoscale is like microscale, only even smaller. In this scale, there is no piece small enough to represent a minifig. The Star Destroyer from the 10143 Death Star set is an example of nanoscale.
Parts Draft: A parts draft involves each participant purchasing a copy of the same set. The elements in these sets are sorted, with all copies of a certain color/element combination forming a ‘batch’. Participants then take turns selecting a single batch to keep. Parts drafts allow LEGO enthusiasts to obtain particular elements in higher quantities than they might be able to obtain otherwise.
Pick-A-Brick: Pick-A-Brick (or PAB) is a service provided at LEGO retail stores where particular elements are stored in containers on a wall.

Signature Figure: A signature figure (or sig fig) is a minifigure used by a LEGO enthusiast to represent him- or herself. Often, photographs of signature figures are used as avatars on online forums and other LEGO-related sites.
Speed Build: A speed build is a competition where small teams of builders are challenged to construct an official (and typically, very large) LEGO set as quickly as possible.
Studs Not On Top: Studs not on top (or SNOT) refers to a body of specialized building techniques that allow LEGO elements to be incorporated into MOCs on their sides or even upside down in order to obtain the shape or effect desired by the builder. This style of building is different from the traditional method of building with all of the pieces right-side-up, hence the name.
Teen Fan of LEGO: A teen fan of LEGO (or teenage fan of LEGO, or TFOL) is a LEGO enthusiast who is between the ages of 14 and 17. Unlike kid fans of LEGO, teen fans of LEGO can legally participate in online forums and other LEGO-related sites, and are often allowed to join LUGs.
TLC: TLC stands for The LEGO Company (sometimes called "The LEGO Group of Companies" or other names depending on the country and the legal regulations of that country.) While the single word "LEGO" can refer to the LEGO Company, fans sometimes use the acronym "TLC" instead, since the word "LEGO" can also refer to the products made by the LEGO Company.
