Having someone nag you while giving you directions. Usually while driving. Usually a wife.
We'll be there in a bit, I'm driving and my wife will nagigate the whole way.

My wife thought we were lost and nagigated until we finally parked.

Stop freakin' nagigating, I know where I'm going.

Get the Nagigate mug.
When a friend or spouse is supposed to help you with directions but, instead, constantly makes negative comments about your driving.
My wife was the nagigator on our trip to the beach.

When the co-pilot in a car is very annoying in the way in which they give directions.
person in passenger seat: Make a u-turn in 500 feet, and then take a left, and don't speed, you're going way too fast! Didn't you see that sign? Damn, you missed the turn, what's wrong with you?!

driver: Jeez, stop being such a nagigator..
