The code of "pushback"

Inevitably, in a world full of ideas, meetings and political correctness, you'll hear someone "pushback."

Whenever someone throws an idea into the ether, another will pop up their hand and ask if they can offer "pushback."

But, is "pushback" just PC for I-think-your-idea-sucks or I-actually-think-your-a-bit-of-dick?

I would like to say that this isn't the case, but when the sugar-coating is removed, is this all that you're left with?
