How it's used
Using this term for money is a nostalgic nod to the green ten dollar paper notes that were common in circulation decades ago. While the physical notes have largely been replaced by plastic ones or coins, the slang persists among older generations. Context is vital because it is equally likely to refer to the actual crustacean in a culinary setting.

Common mistake
Do not assume a speaker is talking about food if you are in a casual conversation about money or betting, as the slang meaning is still quite recognizable.
