If enough people make a language mistake, it becomes a rule.

I mean I get your point and for all intents and purposes I don't even necessarily disagree.

I just wanted to add this little factoid, since I think using "octopi" instead of the at least equally as correct "octopuses" shows that one tries to follow the etymology of the word.
And if you try to do that, the etymologically correct plural is "octopodes".

Then again I hesitated even answering you, since I am by no means one of those weirdos that has a problem with language changing.

For all I care we can talk about octopussies and octopiarians or whatever, but as someone that had to learn latin as a child, the use of octopi just kind of itches my brain.

But it is all good, I get what you are saying and my first post was never meant as a negative critique of OP and more as a fun fact.
