LEGO Acronyms & AFOL Lingo

Here’s a collection of words, phrases and abbreviations you might hear when speaking to an AFOL (Adult Fan Of LEGO) (special thanks to www.the brickblogger.com and www.brothers-bricks.com for some of these):

A

  • ABS: “Acrylonitrile Butadiene Styrene”. The type of plastic that LEGO bricks are made from. Far from being a government controlled substance, this form of ABS is readily available in every shopping mall and is even sold to children in the form of boxes filled with small brightly colored rectangular pellets, and has caused more misery and suffering in the world than the opium epidemics of the 19th century.
  • AFOL: “Adult-Fan-of-LEGO”.  The most common term used to refer to LEGO fans who are adults. Generally pronounced “ay-foal.”
  • AHOL: “Adult Hobbyist of LEGO”. The H is sometimes interchanged with another word not defined here. This generally refers to a buyer of sets, not a builder of MOCs, but not always exclusive.
  • ALE: “Adult LEGO Enthusiast”. Some LEGO fans prefer to be called enthusiasts rather than fans, attempting to avoid the perceived stigma of the word “fanatic.” See also: AFOL
  • Ambassador: The title given to fan liaisons who represent fan organizations within the LAN.
  • Anti-Stud: The indentation in the bottom of bricks and plates which serves as a stud receptacle and is one half of the mechanism by which LEGO pieces interlock.

B

  • Bignette: a large LEGO creation (larger than a Vignette, but smaller than a Diorama).
  • Blay/Bley: “Bluish Gray/Grey” refers to the current LEGO gray/grey, compared to the old version “Old Gray/Grey”.
  • Brick: A universal name for a LEGO piece, regardless of shape or color. Also: In LEGO element taxonomy, any roughly cubic LEGO piece which is 3 or more plates tall. Also: In technical terms, used to refer a specific piece shape, regardless of color. Contrast with Element.
  • Brick-Built: a LEGO creation that is composed of basic LEGO elements, instead of more specialized elements. (For example brick built figures, animals, or objects.)
  • Builder: A LEGO fan whose primary interest is building MOCs. Contrast with Collector, though many fans are both collectors and builders.
  • BURP: “Big-Ugly-Rock-Piece”

C

  • Cheese Slope: a LEGO part with a 33° slope, 1×1 stud wide and 2 plates high. It is named after the fact that yellow pieces look like a wedge of cheese.
  • Clone: construction toys similar and often compatible with LEGO, but cheaper in quality and price, designed to compete with the LEGO brand. They are often greatly despised by LEGO-fans and sometimes referred to as fakos.
  • Collector: A LEGO fan whose primary interest is collecting official sets. Contrast with Builder, though many fans are both collectors and builders.
  • Custom: a LEGO creation or individual element that uses non-LEGO parts or modified parts, or accessories from third-party vendors like LifeLites and BrickForge. Contrast with Purist.
  • Customizer: a LEGO-fan who is not afraid to modify LEGO parts. Customizing may include painting, cutting, drilling, melting LEGO elements, adding other non-LEGO parts to a creation, or adding details with custom-made stickers and decals. These are all considered herecy by a “purist”.

D

  • Diorama: a very large LEGO scene, larger than a Bignette or Vignette.

T

  • Tablescrap: A small, clever build that doesn’t stand alone as a completed creation. From “table scraps,” i.e. leftovers. A tablescrap may be a simple exploration of a technique (such as an interesting way to combine several elements to make an odd shape), or may be a recognizable item that’s just too small to merit presentation on its own (such as a minifigure chair). Many builders set aside their tablescraps and save them for use in future creations.

#

  • 8-Wide: Refers to the width of train locomotives and rolling stock as 8 studs wide which roughly translates to 1:48 scale. This is the most popular LEGO train scale among enthusiasts.
  • 10-wide: Refers to the width of train locomotives and rolling stock as 10 studs wide which roughly translates to 1:38 scale and matches scale with the width between standard LEGO train track elements. Builders in this scale are often referred to as 10-Wide Master Race because of their elitist attitudes towards other scales. Nicknamed “The One True Scale”, 1:38, or the least popular LGP (L-Gauge Proto).
