the straw that broke the camel's back

Tipping point event

The straw that broke the camel's back is the final small burden that causes a collapse or breaking point after many others have accumulated.

The phrase captures how minor additions can trigger major consequences when capacity is already strained: I could handle the delays and the cost overruns, but losing the permit was the straw that broke the camel's back.

Often shortened to the last straw.
