Two baseball players who are so close to each other they do everything together, like walk down to baseball practice together, go get Jamba Juice together, share deoderant in the locker room, are in each other's fave 5, and slap each others' butts after every play; like a bromance, but specificlly for baseball guys.
Robyn: "Hey, what's up with Alika and AJ? They're always doing stuff together!"
Jennifer: "Yeah, that's cause they have a basebromance."
