Nail his/your pecker to a fence post.
A very painful and embarrassing way to make a point, like when someone’s pecker is nailed to a fence post and they can’t move.
My dad said, 'If you don’t clean your room, I’ll nail your pecker to a fence post.'
He yelled at the kid, 'I’ll nail your pecker to a fence post if you don’t stop being a brat.'
She said to her friend, 'I’d nail your pecker to a fence post if you didn’t leave my shoes everywhere.'
