I've been using English as my first language for nearly 20 years and am unfamiliar with "yoinker".

Just googled it and, ... nah, I wouldn't approve that PR!

(Have never heard it used down here in Australia. We've got plenty of other sayings that are local to us though.)

Hehe, I never googled yoinker until just now. I originally heard it on The Simpsons. Here's a SFW Simpsons supercut of "yoink":

I suspect there are a lot of words that used to be safe that are less so now :P
