[Idiom] LAST STRAW. - Understand How Last Straw Leads to Major Decisions
Last straw.
The final problem that causes a reaction.
The phrase "the last straw" comes from a longer expression, "the last straw that breaks the camel's back." It refers to the final, small problem in a series of bad occurrences that finally makes someone lose their temper or patience. The metaphor suggests that, like a camel being overloaded until a single straw is too much, people also have limits to what they can bear.
