Nagivator
A Nagivator is someone who constantly second-guesses you, yells at you, and acts like they know the way better than you do, even though they probably got lost in the parking lot.
My dad thinks he’s a pro, but he gets confused by a stop sign and starts screaming, ‘Turn left now or we’ll die!’
My sister says, ‘I told you to take the second exit!’ while I’m trying to parallel park.
My brother yells, ‘You missed the turn! I saw it coming!’ even though he was asleep the whole time.
