On a reason trip to UK and Czech, I have noticed that there are more freeballers in Czech than UK. Some are very obvious in white pants, jersey shorts and low rise jeans. Amazingly, some middle eastern guys and africans were freeballing too.
The taxi driver was one of them with clear definition. His explanation was summers may not be hot and when it is every one makes full use of it. I guess free balling is getting more common.
