NINJA 

A business acronym for "Need Information, Not Just Advice."

An admonition to provide objective and fact-based data, not subjective opinions.

"Joe keeps telling Dave how American cars are so crappy and unreliable, really slamming them. So now, every time, Dave is like, NINJA, NINJA! Have some real facts ready, or shut up!"
