“A semi-pejorative term for polystyrene plastic figurines and miniature model kits made for tabletop role-playing games and wargame simulations, particularly the popular Games Workshop Warhammer Fantasy and Warhammer 40,000 lines. The “crack” designation applies in that fans of these types of games seem “addicted” to them like a drug, and crave buying, assembling, and painting the models, spending large amounts of money and time in doing so, and anxiously await the latest, most finely-detailed releases.”  — Urban Dictionary
