What does that's the last straw of Phillip mean?

Answer 1

It means that is your last chance you have gotten on my nerves too many times and you just blew your last chance. There is a old saying: "The straw that broke the camel's back." Camels are reputed to be able to carry massive load, often more than a wagon can. But great as the carrying capacity of a camel is you can still over-load him. One such example is of gradually adding single strands of straw to a camel until you effect a weight that will 'break the camel's' back. This final straw has been likened to the cummulative effects of insults or out-rages that a tolerant ruler will no longer abide.
The saying "the straw that broke the camel's back" means that if you pile enough of anything up, it will become too heavy eventually.

This has become a saying meaning "I have too much to do, and I am stressing out."

The saying "that's the last straw" comes from that original saying, and means "That's it, I have had enough!"

They are saying that whatever just happened WAS the straw that broke the camel's back.
The phrase the last straw asks us to imagine that we are loading various burdens onto a camel, so the camel can transport them for us, and we put on more and more, to the limit of the camel's strength, and in the end, we just add one straw (which weighs almost nothing) but since we have reached the limit of the camel's strength, that last straw is too much, and the camel collapses. So the last straw is the final burden that is too much to bear.
The long version of this idiom is, "The final straw that broke the camel's back." This isn't a drinking straw, it's like hay. Imagine you're in the desert, and you need a camel to carry your straw. You load it on, and on, and on, it starts buckling it's legs BUT it fits. You put on just one more straw and it breaks the camel's back. The straws are supposed to be mistake. Every time you do something bad, you're adding a straw to the camel's back. You did one last thing.. And it broke the camel's back. It's not that one thing that gets you grounded or fired or expelled or whatever, it's the combined crimes you commited: All the straw.
it means you are very angry and have had enough It refers to the straw that broke the camel's back, because the camel is already carrying its maximum weight of straw before one more straw is added, and it is used as a metaphor for the last provocation before patience is exhausted.
