A terrible hockey player who gets called for multiple penalties in a single game or period and spends most of the game in the nest. A J Bird costs a hockey team the game because he is in the nest so much, but they forgive him because of their hot sister.
Can you believe that J Bird got called for intent of slashing and is getting sent to the nest.
