Todd Frazier isn't great with names, so he's calling all of his new teammates 'Big Dog'

He hails from New Jersey, attended Rutgers, loves pro wrestling and his nickname is "The ToddFather." Yup, Todd Frazier is basically New York personified -- which is why it's perfect that he's gone from the Yankees to the Mets. 
Even though his new team is just across the city, he still has a lot of new names to learn. That is why he's doing the classic move of calling everyone "Big Dog" -- which may even be a wrestling reference!

It'll be like being at every house party ever: "Hey big dog, need a sports drink?" "Hey big dog, want me to grab you a sandwich?" "Yo, big dog! Let's hit some dingers and then hit up that jacuzzi!"
