That wonderful red stuff that is close to so many of our hearts is the “definition” of

so many slang terms!

For example:

• Badminton (mid-19c)
• Blood (1910s-40s)
• Bucket of Blood (1940s)
• Hemorrhage (1940s)
• Hobo Soup (when mixed with water)
• Red Lead (1920s military use - based on red lead paint for navy usage)
• Red-eye (1920s-60s)
• Red paint (1900s-30)
