last straw, the

the last straw

The final problem, setback, or source of irritation in a series that causes one to finally lose patience or for something to stop working. A shortening of the proverb "it is the last straw that breaks the camel's back." I've been a good sport about letting Tom share the credit for my work, but this is the last straw! I'm finally going to expose him for the liar he is. OK, that's the last straw, kids! I told you to stop shouting back there, and now I'm turning this car around.

last straw, the

The final annoyance or setback, which even though minor makes one lose patience. For example, I could put up with his delays and missed deadlines, but when he claimed the work was unimportant-that was the last straw! This term is a shortening of the straw that broke the camel's back, which conveys a vivid image of an overloaded animal being given one slight additional weight. The expression dates from the mid-1800s, and replaced the earlier the last feather that breaks the horse's back.
