Rubber fetishism is similar to leather fetishism, in that it revolves around clothing made of rubber, latex, PVC, polyurethane, etc. 

The Rubber Pride flag has existed since 1994, developed by Peter Tolos and Scott Moats. It was created by the two during a Vulcan America meeting in the hopes it could be used for rubber enthusiasts to find like-minded partners. Since the Rubber community is significantly smaller than the Leather or Bear communities, and its members tend not to wear their gear in public, it was especially difficult for fetishists to find each other.

The flags designers wanted something different from the uniform horizontal stripes that had become standard for pride flags, so they chose a black base with red and yellow for their brightness. 

Instead of using straight bars they added the zigzag to make a ‘V’ (since it had come out of a Vulcan America meeting) and also because the flag indicates a kink.
