nagbastard
a line worker with a face like a bull and a voice like a screaming goat who thinks they're the boss and yells at everyone else like they're stupid.
Nagbastard: 'I said 30 units! Why are you still packing?'
Nagbastard: 'You think you're on the line? You're just a meat sack!'
Nagbastard: 'I don't need no stinking help from you guys!'
