 He says it helps to understand the original slang, Sidon. When you see young fellows pulling up in their cars and they're trying to look cool and all that stuff, and it was just the way that you kind of lean back towards the side. It was generally called Sidon. Showing off, in other words. The side show was basically a show of show-offs. It was folks that were out there showing off what they were up to, what they were doing, styles, creativity, and what they were doing with their cars, fashion. All that stuff was happening out there at side shows.
