You guys and girls have never driven around the same area over and over again just so people can check out your car. It's something I did alot as a 17/18 yr old with a few mates around Freo, Hillarys and Scabs.
In my home town it was referred to as a "blockie", meaning that you drove around and around the main city block past all the local hoons that were parked in the centre parking spaces in one of the streets.
I'm almost afraid to ask, but what on earth does the term "bog" mean in a bog lap??
