The expression “can of worms” is an increasingly popular phrase in English meaning “a source of unforeseen and troublesome complexity.”
The phrase originated in the United States in the 1950s when bait stores would sell cans of worms.
The fishermen that bought these cans found them very easy to open and yet they were surprisingly difficult to close. As a result, there was a good chance that the worms would take advantage of their newfound freedom and escape.
Nowadays the expression is used not only to apply to a literal can of worms, but also to anything that unexpectedly becomes troublesome and complex. This expression is commonly used in conversation or in writing to refer to a topic that could possibly become very complex and start an argument. Here is how it would be used.
