I have seen people use both phrases (and I have even used the first phrase many times) to mean that something is out of scope/not relevant to the topic at hand. Say your teacher gives you an essay on the French Revolution and you end up writing a whole section on the American Revolution; your teacher would say that the essay was "out of point".
I have looked up these two phrases online, and the former is not listed in any dictionary. The second phrase is only found here. Both of the phrases are used by people on Twitter, but I have not found an authoritative source on either of them.
Can somebody confirm the usage of the two phrases please?
Edit: in Maltese English, "out of point" is used very commonly, so I suppose the phrase is very much in use in Malta, however I am more concerned with the usage of the phrases in other forms of English (British/American and the rest).
