People are cliquey, have odd ideas and tend to like to associate with like minded individuals with common interests. When some of these people get together they form bands, political parties or gangs with stupid tattoos.
Others, like the Ulysses Club, a motorcycle club where you need to be 40+ to join as a junior member and whose motto is “Grow Old Disgracefully”, are quite happy to take the mickey out of themselves.
Others groups tend to take themselves more seriously. I discovered yesterday not only a Punk counter-culture but that there are members of said group in Canberra. Bearing markings from a bad Vin Diesel film, followers of the Straight Edge life style are hard core punks who abstain from grog, smoking, other drugs (including caffeine) and some even to the extent of meat and sex (I’m assuming individually and/or together).
Let us know what else is out there, from the light-hearted to super-serious.
