The Biohazard Sign (☣) is an internationally recognized warning symbol indicating biological substances that pose a threat to living organisms. Added to Unicode in 1993, it frequently appears in digital spaces to denote literal health hazards, pandemic discussions, or jokingly to describe a highly "toxic" person or situation. Social media users and gamers also use it to highlight edgy aesthetics, survival gameplay, or metaphorical toxicity.
