People in Thailand have started a strange trend: they form gangs that mimic Mexican gangs with the one notable exception that the Thai gangs don't seem to be involved in crime. They just like to get together, dress up like Mexican gangsters and have a few drinks with each other. Most of them seem to have ordinary day jobs, but once they're out of work, a different side of them comes out.
The people that do it describe being in a "Mexican gang" as empowering and liberating. They also say that their friends and family are a combination of concerned and baffled.
If you know of a weirder cultural trend, we'd like to hear about it.
