You have a door that's built of steel, has a physical and biometric lock, requires a 16 digit password, probably withstands a grenade. Grab a (pick) axe and hack through a wall or window instead.
Someone hacking a tunnel to get to work faster, we respect their will, creativity, and that hint of rebelliousness.
For the pejorative, it's someone thuglike. A hacker isn't a professional lockpicker. They're just hitting every wall with an axe. There's no finesse, even among criminals. But they're also the reason you don't have windows; why you need to use special characters and numbers in your password.
