A hockey player who is so bad they make the team look like a group of brainless sloths.

My brother is a jackamoe. He missed the goal and got tackled by the other team.

My friend said I'm a jackamoe because I fell down during the game.

My cousin is a jackamoe. He didn't even know how to pass the puck.
