A Shepharding
A Shepharding is a guy who talks like a broken robot, never gets mad, and acts like he's the toughest man alive, even though he's probably scared of a loud noise.
'Hey bro, I just watched you fail three times in a row and you still said nothing. You're a Shepharding.'
My cousin is a Shepharding. He didn't even blink when his dog bit his brother's face off.
I asked him why he never yells and he said, 'I don’t want to seem weak.' I told him, 'You're not weak, you're just boring.'
