Biohazard Tattoo 

Tattoo symbol with 3 interlocking circles with another circle in the middle.

The biohazard symbol was created to identify hazardous substances back in the 60's but is now part of popular culture. As a tattoo it was popularized by the band Biohazard.

It has been adopted by many in the gay and HIV+ communities to identify people with HIV/AIDS to their potential sexual partners.

That dude's got a biohazard tattoo. He's either a hardcore social reject or he has AIDS!
