Wow, it’s one of my favourite things to say! @cryotosensei can confirm. 

It’s Australian slang that means that you’re here for serious business, see [this article](https://battleoflongtan.com/not-here-to-fuck-spiders/).

Edit: Ok, that was a quite short article. [Here](https://www.urbandictionary.com/define.php?term=Not%20here%20to%20Fuck%20Spiders) is the definition from Urban Dictionary.
