:* '''Graffiti''' - Some skateboarders are known to spray graffiti in places where they like to frequently skate. Skateparks are sometimes covered on all surfaces by graffiti sometimes depicting satanist or antisocial imagery or offensive slogans and captions.  This began in the early 1980s and stayed within a tiny minority of the skateboarding population, who listened to heavy metal bands including Black Sabbath and Iron Maiden.  The perception of a link between satanism and cults with skateboarding became so prevalent, it was later mocked by the skateboarding populous in the late 1980s and early 1990s with skateboard graphics featuring Winnie the Pooh with sunglasses, devilish horns and a trident on skateboard company World Industries' owner Steve Rocco's deck and t-shirt.  Other common themes and images included "ending racism" as scrawled on the bottom of professional skateboarder Tommy Guerrero in the 1989 Powell Peralta video "Ban This."  Many abandoned concrete pools were generally painted with spray paint by both frequent skaters and graffiti "artists" who had nothing to do with the sport.  Concrete is generally considered by graffiti artists, taggers and vandals as the best surface on which to spray paint as wood or plastic causes heavy dripping for the thin aerosol-based coloring.
