“快乐的罗杰”英文全称不要HAPPY HERO的答案

叫做Jolly Roger
The Jolly Roger is the name now given to any of various flags flown to identify a ship's crew as pirates.The most famous Jolly Roger today is the Skull and Crossbones,a skull over two long bones set in an X arrangement on a black field.Historically,the flag was flown to induce pirates' victims to surrender readily.
Since the decline of piracy,various military units have used the Jolly Roger,usually in skull-and-crossbones design,as a unit identification insignia or a victory flag to ascribe to themselves the proverbial ferocity and toughness of pirates.
