A baseball booty is a baseball players butt when he's in his uniform. Most baseball booties are kind of perky and big but they don't look like a girl butt. Baseball booties are awesome, but not every player has one (at least not a good one)
Girl 1: "Did you see his butt! It looks fine in those baseball pants!"
Girl 2: "Yea! Man, he has a great baseball booty!"
