What is a VIB/AFOL? AFOL means Adult Fan Of LEGO and we affectionately refer to AFOLs who attend Bricks LA as VIBs – Very Important Builders. VIBs create the brick built models that are displayed all weekend at Bricks LA. VIBs can also participate in games and activities throughout the weekend designed to test their skills and and have fun with other adult LEGO fans. You can find more details of what to expect as a VIB at Bricks LA in our Very Important Builder Guide.
