What do you call the guys that complain about non stock cars?

In the Aircooled VW world we called them "Stock Nazis"
Now that Im back into Mopars I dont think that fits.
So - whats your favorite saying to the guys that complain when they see your car is not stock?
What do you call them?
You know the ones that cant keep there mouth shut about your Hood Scoop
or front end from a 69 when the car is a 70.

If you are one of "those guys" what do you call yourself?

Not trying to start an argument LOL!
Just quirious after I saw a post on a mopar FB page and someone complaining that the car in question had a hood scoop on it but otherwise looked stock.

I call them their name. There's always going to be a critic. If their name's not on the title it's just typical background noise.
