The AFOL Slang Dictionary

The online LEGO community has spent over 12 months compiling a comprehensive AFOL (Adult LEGO Enthusiast) Slang Dictionary to document the unique, descriptive, and often comedic terminology used by builders around the world. While general LEGO glossaries exist on sites like The Brothers Brick and Firestar Toys, this newly compiled resource focuses specifically on localized and community-specific slang terms for various elements and concepts. The project references official BrickLink part numbers and images to help builders identify the exact pieces being described.

The dictionary reveals a fascinating array of regional and creative nicknames for specific LEGO components based on their shape or community history. For example, the curved slope piece (54200) is widely known as the Andersen Wedge after its creator Henrik Andersen, alongside other names like the cheese slope or slanty thing. Similarly, the 1 x 1 round plate with an open stud (85861) attracts creative monikers such as the Apollo Stud—a mishearing of "hollow stud"—as well as bagel and polo plate. Regional terms also feature heavily, such as the Dutch "Bankjes" for panel pieces (4865) and German acronyms like AZMEP and AVMEP for specific jumper plates. The glossary even includes acronyms like ARSE, which stands for Assorted Random Shit Elements, and notes social events like Australia's BEGO Night, which stands for Beer and LEGO Night.

Because the dictionary relies on contributions from builders globally, the publisher encourages fans to add missing terms in the comments section so the glossary can continue to grow and evolve. The creator also includes a language warning, noting that reader discretion is advised due to some adult-natured terms included in the complete A-to-Z list.

As you dive into your own building projects or organize your collection using a LEGO storage box, exploring these community-driven slang terms offers a fun glimpse into the shared culture of adult LEGO builders worldwide.
