Nagdometer
A digital sign that watches you like a hawk and won’t stop until you pay it.
That nagdometer just watched me for a whole block and finally flashed me for doing 35 in a 25.
I was going 50 in a 30, and the nagdometer said, 'You’re not even trying.'
The nagdometer on the highway just said, 'I’m watching you, and I’m not done yet.'
