One of the standard explanations and examples I use when teaching the mechanics module of A Level is to consider driving a car around town. Most pupils have experienced, or are aware, of people thier age who drive circuits around the local town trying to get noticed. I used to just talk about this practice but a few months back a friend was talking about his teenage experience of this form of behaviour and he used the term:
This term didn’t really need any explaination as I already knew what it meant. I’ve never really partaken in the the Barry Lap experience. I think the closest I got was riding around Bishop’s Stortford on my Honda NTV 650 with Daryl on his Silverwing just after we had set up radio communication between us. We went around town a few times chatting to each other on the way. Being able to easily communicate between different bikes was far more of a novalty than trying to get attention from onlookers. This was in 1999 and quite before either of us owned mobile phones.
Anyway, I hope that with my continued use that the term Barry Lap might one day make it into the OED!
