Lego Kfol / Afol / Tfol Terms

LEGO Glossary

AFOL

Adult Fan of LEGO. The most common term used to refer to LEGO fans who are adults. Generally pronounced to rhyme with “hay-foal.” See also ALE and ALH.

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 AFOL.

ALH

Adult LEGO Hobbyist. Another alternative self-descriptive name preferred by some LEGO fans over AFOL or ALE

Bandwagon

A passing LEGO fad, such as cave racers or IATTAR.

Brick-Built

A LEGO creation or portion of a larger creation that is composed of multiple LEGO elements even when a larger, pre-fabricated LEGO element or custom accessory may be available. Solving a LEGO problem through brick-built means is generally respected more than using a prefabricated or custom element.

BURP

Cheese Slope

A LEGO element with a 33° slope, 1 stud by 1 stud wide and two plates high (or 2/3 of a brick high). Part number 50746. Useful for adding fine detail to LEGO creations. Named after the fact that yellow and orange pieces look like a wedge of Cheddar cheese.

Clone

Construction toys “compatible” with LEGO created and sold at lower cost, designed to compete with LEGO brand building bricks. Considered off-limits by most LEGO fans.

An easy way to get the parts you want in larger quantities without buying multiple copies of the set yourself. Read more on SEALUG.org.

FBTB

From Bricks to Bothans. A LEGO Star Wars fan site and online community.

Pseudo-technical detail added to a LEGO creation to enhance its appearance. Frequently seen in LEGO space and mecha creations.

LEGO building techniques that break the “rules” for connections between LEGO elements used by official LEGO set designers — particularly connections that stress the LEGO elements. For example, inserting a plate between the studs on a brick.

LUG

LEGO Users Group. Initially used to describe a local or regional LEGO club that met and interacted primarily in an offline or “real world” context, the term LUG has been extended to include virtual and even ephemeral groups of LEGO fans, such as JLUG, ChiefLUG, and KiethLUG. Many LUGs now also have an online presence, further blurring the line between traditional LUGs and online LEGO fan communities.

MOC

My Own Creation. Any LEGO creation designed and built by a LEGO fan without instructions. Generally pronounced “mock.”
