Here's how it evolved:
* "Bodkin" was originally a type of small dagger or awl.
* "Odd" simply means strange or unusual.
* Putting them together creates an expression of surprise or bewilderment.
Think of it like someone saying, "Odd bodkins! Where did that come from?" It's a playful way to express surprise or confusion.
It's important to note that "odd bodkins" is a bit of a niche expression, often used in a humorous or dramatic context. It's not something you'd hear in everyday conversation.
