look up any word, like fuck boy:
Intense rage accompanied by retard strength to create superhuman powers. Yinzer rage stems from extreme anger and frustration. It's better not to fuck with someone with yinzer rage, because they will likely kill someone. This term is only relevant to males in Pittsburgh with the yinz accent.
He has yinzer rage.

Dude, he is just raging right now! It has to be yinzer rage.
