ZF 

ZF, also known as the ZF clan or Zero Fucks clan, is a community of gamers from all over the world, who are known for their dirty humour and a wide spectrum of ridiculousness. The YouTuber and livestreamer who goes by the name of SovietWomble is often portrayed as their face and mascot, along with several other names. A lot of them stream and have their own audiences, but they are known to reference eachother quite often.

ZF should really get more members!
