skull and crossbones

☠️ The skull and crossbones is a classic symbol of death, danger, and poison. Originating from historical use to mark toxic substances, this emoji now broadly signifies danger, lethality, toxicity, or extreme hazard. In online culture, it's often used to convey meanings like "toxic," "danger warning," "deadly," or "extremely bad," carrying strong negative and cautionary tones. It can also be employed humorously or hyperbolically to describe something as "toxic" or "deadly," such as a bad joke or a crushing situation.
