Fenway - Bambino (his middle name - from Babe Ruth who was traded to the dreaded Yankees and cursed the Red Sox until a few years ago).

Dirt Dog - Because he loves to dig in the dirt and get all dirty and he loves to "go to ground" looking for vermin (also Dirt Dog is a nickname for the Red Sox which I didn't know until AFTER I started calling him that).

Pooh Bear - because he's a cuddly wittle bear.

MR. Fenway - his "formal name"

Love Bug - beause he's a wittle love bug when he gives kisses and cuddles.
