Sororities or similar organisations in Germany?

[excelblue]

Sororities in Germany are like "autobahns" in the US. You can find a highway that looks like an autobahn and is probably built better, but you'll be disappointed the minute you see that 80mph speed limit, even though nobody follows it. Basically, just like how a no-speed-limit autobahn is a German thing, the Greek system is a distinctly American thing. There are social organizations that come close, but not exactly.
