B.Ā.B.
A ship name or a show, but mostly it's a way to say Booth and Brennen are the main characters in a show called Bones, and they're probably going to solve a murder.
B&B is the show where Booth and Brennen solve crimes like it's their job.
I watched B&B and I was like, 'These people are good at their job.'
B&B is the show where the main characters are always arguing and solving crimes.
